    Heterogeneous Wireless Sensor Networks Using CoAP and SMS to Predict Natural Disasters2017Ingår i: Proceedings of the 2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS): The 8th IEEE INFOCOM International Workshop on Mobility Management in the Networks of the Future World (MobiWorld'17),, Piscataway, NJ: IEEE Communications Society, 2017, s. 30-35Konferensbidrag (Refereegranskat)
    Abstract [en]

    Even in the 21 st century human is still handicapped with natural disaster. Flood is one of the most catastrophic natural disasters. Early warnings help people to take necessary steps to save human lives and properties. Sensors can be used to provide more accurate early warnings due to possibilities of capturing more detail data of surrounding nature. Recent advantages in protocol standardization and cost effectiveness of sensors it is possible to easily deploy and manage sensors in large scale. In this paper, a heterogeneous wireless sensor network is proposed and evaluated to predict natural disaster like flood. In this network CoAP is used as a unified application layer protocol for exchanging sensor data. Therefore, CoAP over SMS protocol is used for exchanging sensor data. Furthermore, the effectiveness of the heterogeneous wireless sensor network for predicting natural disaster is presented in this paper.

    Platform independent system integration2011Ingår i: SAE 2011 World Congress & Exhibition Technical Papers: April 12 - 14, 2011, Detroit, Michigan, USA ; [papers], Warrendale, Pa: Society of Automotive Engineers, Incorporated , 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents and demonstrates a paradigm to implement automotive systems based on their specifications in a manner that is platform independent. The advantage is to have the same software used in simulation as on different types of micro-controller in a vehicle as well as to ease the integration of different systems. The paradigm is to model the system’s components as reactive objects and to use the Timber kernel to schedule their (re)actions. The demonstration is done by developing an anti-lock braking system within the simulation software CarSim and Simulink, which is then evaluated on a braking maneuver over a surface with different coefficient of adhesion from side to side (split mu).

    Hybrid modeling and co-simulation of district heating systems with distributed energy resources2014Ingår i: Workshop on modeling and simulation of cyber-physical energy systems, MSCPES 2014: held as part of CPS week, proceedings, Piscataway, NJ: IEEE Communications Society, 2014, artikel-id 6842395Konferensbidrag (Refereegranskat)
    Abstract [en]

    While there is intense global research activity addressing problems underpinning the re-engineering of the electrical power grid, thermal energy grids are likely to play an increasing role in energy systems. This paper describes an on-going effort in hybrid modeling and co-simulation of the physical and control domains of district heating networks. The focus is on modeling each domain using semantics and tools natural to each; we also describe the challenges of, and a method for, integration and synchronization of the simulation models in each domain. Here, the dataflow model of computation used by Simulink provides a flexible industry-grade environment for modeling the dynamics of heat energy flows, and the IEC 61499 automation architecture facilitates distributed systems modeling and enables rapid deployment to field hardware. At the application level, we show how this framework enables the study of energy flows within a producer/consumer (prosumer) and the analysis of the economic value of integrating distributed solar thermal generation and storage into a prosumer participating in a district heating network

    Abstract [en]

    This paper presents an automatic software generation method for energy distribution automation. The method uses the distribution network structure represented in SCL format of the IEC 61850 standard and generates complete executable applications compliant with the IEC 61499 standard. Each equipment element is based on the componentized MVC design pattern and can be executed on a distributed network of HMI and control devices. The challenges solved in this work include design and automatic generation of a library of substation equipment elements according to the MVC design pattern and secondly, automatic generation of SCADA HMI based on the IEC 61850 specification. The design process is demonstrated in a laboratory case study.

    Bridging Service-Oriented Architecture and IEC 61499 for Flexibility and Interoperability2015Ingår i: IEEE Transactions on Industrial Informatics, ISSN 1551-3203, E-ISSN 1941-0050, Vol. 11, nr 3, s. 771-781Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In recent years, requirements for interoperability, flexibility, and reconfigurability of complex automation industry applications have increased dramatically. The adoption of service-oriented architectures (SOAs) could be a feasible solution to meet these challenges. The IEC 61499 standard defines a set of management commands, which provides the capability of dynamic reconfiguration without affecting normal operation. In this paper, a formal model is proposed for the application of SOAs in the distributed automation domain in order to achieve flexible automation systems. Practical scenarios of applying SOA in industrial automation are discussed. In order to support the SOA IEC 61499 model, a service-based execution environment architecture is proposed. One main characteristic of flexibility-dynamic reconfiguration-is also demonstrated using a case study example.

    Application of visual specifications for verification of distributed controllers2013Ingår i: E-systems and e-man for cybernetics in cyberspace, Piscataway, NJ: IEEE Communications Society, 2013, Vol. 1, s. 646-651Konferensbidrag (Refereegranskat)
    Abstract [en]

    In a search of an appropriate visual specification language to be applied in control engineering the timing diagram specification language is suggested. It is applied to the verification of distributed controllers following the standard IEC 61499. Specification of inputs and outputs of the controller are given in the graphical form of signal diagrams. The inputs are then converted into finite-state models, while the diagram of outputs is used to build equivalent analytic expressions in extended CTL. These two parts are used in formal verification of the control system.

    System-level architecture for building automation systems: Object-orientated design and simulation2013Ingår i: Proceedings of the 39th Annual Conference of the IEEE Industrial Electronics Society, IECON 2013, Vienna, Austria: IEEE Communications Society, 2013, s. 5334-5339Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a novel framework for designing and simulating the decentralized control of Building Management Systems (BMS) in an object-orientated way. The proposed approach follows physical structure of building as a starting point for its automation software development. The architecture proposed enables simulation in the loop with plant model that can be created without extra development efforts. The decentralized control logics of the BMS subsystems can be developed independently from the deployment configurations thanks to the properties of IEC 61499 reference architecture.

    Towards cyber-physical agnosticism by enhancing IEC 61499 with PTIDES model of computations2016Ingår i: Annual Conference of the IEEE Industrial Electronics Society, IECON 2015: Yokohama, Japan, 9-12 Nov. 2015, Piscataway, NJ: IEEE Communications Society, 2016, s. 1970-1975, artikel-id 7392389Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper addresses software design for cyber-physical automation systems that enables invariant properties of the physical system in case of software reallocation to different hardware. The proposed approach is based on the distributed reference architecture of IEC 61499 standard enhanced with a time-stamping mechanism. It is demonstrated that the proposed approach complements the abilities of IEC 61499 to maintain correct causality of distributed system execution with improved performance of physical system property called cyber-physical agnosticism. The time-stamped event semantics of IEC 61499 is introduced and mapped to the PTIDES execution model of Ptolemy II. We have experimentally validated that changing the model of computation in distributed automation to a time-stamped event-driven one can bring substantial improvements in flexibility and reconfigurability of cyber-physical automation systems.

    Abstract [en]

    In this paper we present a prototypical smart metering infrastructure (MI) as part of the “distributed nervous system of SmartGrid”. Proposed MI is enabled with distributed programming infrastructure of the international standards IEC 61499, communication and design infrastructure of IEC 61850. The paper introduces IEC 61850 logical device for the smart meter. Based on this definition, the intelligent logical nodes architecture (iLN) is used to organize the distributed intelligence of a “swarm” of such smart meters. The proposed architecture has been applied to the novel Eaton PowerXpert intelligent commercial grade meter and tested in co-simulation environment.

    The semantics of alarm definitions: enabling systematic reasoning about alarms2012Ingår i: International Journal of Network Management, ISSN 1055-7148, E-ISSN 1099-1190, Vol. 22, nr 3, s. 181-198Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The development and integration of an alarm interface between network elements and a network management system is a costly process, largely because of the informal way in which alarm interfaces are expressed and communicated. Low-quality alarm documentation and confusion around fundamental concepts like alarm states and alarm types are typical consequences of current practices. If alarm interfaces were expressed in a more formal manner, costs could be reduced and more advanced analysis and automation would be enabled. We present a novel approach to alarm interfaces by providing a formal alarm model together with a domain-specific language that allows us to specify both the alarm models and the constraints placed on the alarm models in a consistent manner. This means that we can verify the consistency of an alarm interface and automatically generate artifacts such as alarm correlation rules or alarm documentation based only on the model

    Abstract [en]

    Network Service Providers are struggling to re- duce cost and still improve customer satisfaction. We have looked at three underlying challenges to achieve these goals; an overwhelming flow of low-quality alarms, understanding the structure and quality of the delivered services, and automation of service configuration. This thesis proposes solutions in these areas based on domain-specific languages, data-mining and self- learning. Most of the solutions have been validated based on data from a large service provider.We look at how domain-models can be used to capture explicit knowledge for alarms and services. In addition, we apply data- mining and self-learning techniques to capture tacit knowledge. The validation shows that models improve the quality of alarm and service models, and automatically render functions like root cause correlation, service and SLA status, as well as service configuration automation.The data-mining and self-learning solutions show that we can learn from available decisions made by experts and automatically assign alarm priorities.

    Industry-friendly engineering tools for wireless home automation devices2015Ingår i: IEEE 13th International Conference on Industrial Informatics (INDIN), 2015: Cambridge, United Kingdom, 22-24 July 2015, Piscataway, NJ: IEEE Communications Society, 2015, s. 1174-1179, artikel-id 7281902Konferensbidrag (Refereegranskat)
    Abstract [en]

    Although home automation (HA) systems in the wired domain are widely accepted by consumers, in today's industry, the mega trend is steering HA systems along a wireless way. Theoretically, wireless solutions are able to provide HA systems with more flexibility and thus reducing engineering costs. In practice, however, deploying wireless HA systems actually requires more costs and efforts due to the lack of versatile software tools to support the whole engineering process. This paper defines and evaluates the engineering workflow and architecture for home automation systems. The proposed architecture is studied and implemented based on web technologies and graphical configuration environments, with the aim of reducing workloads of HA engineers at every stage. A prototype has been implemented to demonstrate the technical feasibility of the proposed architecture

    Robust Methods for Automated Selection of Cardiac Signals after Blind Source Separation2018Ingår i: IEEE Transactions on Biomedical Engineering, ISSN 0018-9294, E-ISSN 1558-2531, Vol. 65, nr 10, s. 2248-2258Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: Novel minimum-contact vital signs monitoring techniques like textile or capacitive electrocardiogram (ECG) provide new opportunities for health monitoring. These techniques are sensitive to artifacts and require handling of unstable signal quality. Spatio-temporal Blind Source Separation (BSS) is capable of processing suchlike multichannel signals. However, BSS's permutation indeterminacy requires the selection of the cardiac signal (i.e. the component resembling the electric cardiac activity) after its separation from artifacts. This study evaluates different concepts for solving permutation indeterminacy. Methods: Novel automated component selection routines based on heartbeat detections are compared with standard concepts, as using higher order moments or frequency-domain features, for solving permutation indeterminacy in spatio-temporal BSS. BSS was applied to a textile and a capacitive ECG dataset of healthy subjects performing a motion protocol, and to the MIT-BIH Arrhythmia Database. The performance of the subsequent component selection was evaluated by means of the heartbeat component. Results: The proposed heartbeat-detection-based selection routines significantly outperformed the standard selectors based on Skewness, Kurtosis and frequency-domain features, especially for datasets containing motion artifacts. For arrhythmia data, beat analysis by sparse coding outperformed simple periodicity tests of the detected heartbeats. Conclusions: Component selection routines based on heartbeat detections are capable of reliably selecting cardiac signals after spatio-temporal BSS in case of severe motion artifacts and arrhythmia. Significance: The availability of robust cardiac component selectors for solving permutation indeterminacy facilitates the usage of spatio-temporal BSS to extract cardiac signals in artifact-sensitive minimum-contact vital signs monitoring techniques.

    Sparse Coding of Cardiac Signals for Automated Component Selection after Blind Source Separation2016Ingår i: Computing in cardiology, ISSN 2325-8861, E-ISSN 2325-887X, Vol. 43, s. 785-788, artikel-id 7868860Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Wearable sensor technology like textile electrodes provides novel ambulatory health monitoring solutions but most often goes along with low signal quality. Blind Source Separation (BSS) is capable of extracting the Electrocardiogram (ECG) out of heavily distorted multichannel recordings. However, permutation indeterminacy has to be solved, i.e. the automated selection of the desired BSS output. Accordingly, we exploit the sparsity of the ECG modeled as a spike train of successive heartbeats. A binary code derived from a two-item dictionary fpeak, no peakg and physiological a-priori information temporally represents every BSS output component. The (best) ECG component is automatically selected based on a modified Hamming distance comparing the components’ code with the expected code behavior. Non-standard ECG recordings from ten healthy subjects performing common motions while wearing a sensor garment were subsequently processed in 10 s segments with spatio-temporal BSS. Our sparsity-based selection RCODE achieved 98.1% heart beat detection accuracy (ACC) by selecting a single component each after BSS. Traditional component selection based on higher-order statistics (e.g. skewness) achieved only 67.6% ACC.

    Enabling component-based design for embedded real-time software2009Ingår i: Journal of Computers, ISSN 1796-203X, E-ISSN 1796-203X, Vol. 4, nr 12, s. 1309-1321Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The increasing complexity of embedded software calls for a new, more efficient design approach. A natural choice is to use well-established component-based design; however, its adoption to design of embedded software has been slow and riddled with difficulties. It can be argued that these problems are due to the following peculiarities of embedded systems. Firstly, the tight integration between hardware and software, typical for embedded systems, makes it virtually impossible to model and implement software separately from hardware. Secondly, it is difficult to express timing requirements, an intrinsic part of functionality of many embedded systems, in dataflow abstractions traditionally used in component-based design. We propose to overcome these difficulties by introducing a uniform, consistent modeling of both hardware and software and by integrating timing requirements into the model. We present a modeling framework based on the notions of reactive objects and time-constrained reactions, which enables component-based design of embedded real-time systems. Within this framework, functionality of both hardware and software components is defined in terms of reactions to discrete external events, and timing requirements are specified for each reaction relative to the event that triggered it. We also present a detailed software design methodology for embedded real-time systems based on our modeling framework.

    Personal alarm device: a case study in component-based design of embedded real-time software2011Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Designing software for embedded systems is complicated by such factors as the tight integration between software and hardware, scarceness of available resources, and hard real-time requirements. In our earlier work we proposed a component-based approach based on modeling both hardware and software using reactive objects and time-constrained reactions, which should allow us to overcome these difficulties. We also presented a software design methodology for embedded real-time systems.Here we describe a system developed using this methodology and discuss its advantages. The system is a personal alarm device that should be worn at the waist of a person and that should detect his or her fall and send an alarm signal. The implementation of the system was verified using a Simulink-based simulator. The simulation demonstrated that, even though calculation of acceleration was simplified to allow for an efficient execution on a resource-constrained platform, fall detection remained satisfactory.The case study demonstrates the advantages of the proposed software design methodology, including the fact that functional and timing properties of a system model can be preserved during implementation process by means of a seamless transition between a model and an implementation.

    Evaluating 3-dimensional information visualizaton designs1998Rapport (Övrigt vetenskapligt)
    Abstract [en]

    A number of three-dimensional information visualization designs have been invented during the last years. However, comparisons of such designs have been scarce, making it difficult for application developers to select a suitable design. This paper reports on a case study where three existing visualization designs have been implemented and evaluated. We found that the three visualization designs have inherent problems when used for visualizing different data sets, and that certain tasks can not be supported by the designs. We propose a multi-visualization view to overcome these problems. Finally, the paper also introduces heuristics for selecting information visualization designs

    Cognitive load-control for congested Wireless Sensor Network channels2013Ingår i: 2013 IFIP Wireless Days (WD 2013: Valencia, Spain, 13-15 Nov 2013, Piscataway, NJ: IEEE Communications Society, 2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    Modern wireless sensors transmit at high rates and changing transmission patterns. They may individually or collectively select how much data shall be sent depending on predefined rules tied to properties of measured data. Sending rates thereby change triggered by events appearing in the sensor environment. With wireless technologies such as 802.15.4 (ZigBee) having limited capacity high transmission needs can easily cause overload resulting in decreased throughput. This paper presents a load control mechanism that uses multiple inputs, demand for transmission capacity and perceived quality of each sensor node, to properly configure sending rates of these nodes. The mechanism is based on Fuzzy Logic and quality assessed with utility functions for packet loss and throughput. NS-3 simulation results show clear improvements in overall throughput at high loads with the mechanism compared to without.

    Abstract [en]

    Wireless sensor networks (WSN) commonly use ZigBee to communicate, especially when low power consumption is demanded. ZigBee may however provide unpredictable throughput although transmission distances are short. This is especially evident in difficult environments with complicated reflections and various materials through which radio signals need to pass through. Distributed scheduling based on cognitive networking principles may improve both network predictability and overall throughput. This paper presents measurements of key parameters for such cognitive scheduling, and discusses their potential for predicting suitable per-node transmission rates. Results include variability of throughput, RSSI and LQI observed for different transmission powers, transmission ranges, and number of transmitting nodes.

    Towards implementation of IEC 61850 GOOSE messaging in IEC 61499 environment2013Ingår i: 2013 11th IEEE International Conference on Industrial Informatics (INDIN 2012): Bochum, Germany 29 July - 31 July 2013, Piscataway, NJ: IEEE Communications Society, 2013, s. 464-470Konferensbidrag (Refereegranskat)
    Abstract [en]

    IEC 61850 is the new standard for substation automation. One of the IEC 61850 communication services, designed specifically for protection within the substation automation system is GOOSE messaging. GOOSE messaging is a peer to peer communication protocol aiming to satisfy the stringent communication requirements within protection systems operating over the Ethernet communication framework. One of the on-going research topics in this area is extending capabilities of IEC 61850 to represent control logic by combining it with component software architecture of the IEC 61499 standard. The Intelligent Logical Nodes (iLN) architecture is one such solution which combines the two standards. This development led to the need to implement communication services of IEC 61850 by means of IEC 61499. This paper presents such an implementation of IEC 61850 GOOSE messaging using IEC 61499 Service Interface Function Blocks implemented by means of the WinPCap library.

    This paper presents a visualization architecture to facilitate automated design for distributed automation applications. CAD is used as a source of software models as it was found to provide detailed physical information, particularly for visualization. The approach assumes a fully distributed control architecture, with each system component functionally encapsulated into IEC 61499 Function Block. A baggage handling system is used as a running example throughout this work. Simulation models of the plant were executed in closed-loop with controllers. A corresponding 3D visualization was generated and parameterized based on CAD drawing, then linked to the simulation for a live view of the plant model

    This paper presents a novel model-driven software architecture for systems with high degree of redundancy and modularity of the equipment. The architecture is based on totally decentralized control. It combines adaptability and robustness of multi-agent control architectures with portability and interoperability benefits of IEC 61499 function block architecture. The architecture has been successfully proven feasible on a number of field trials, including modeling and implementation of a medium-scale airport baggage handling control. Deployment was done on distributed networks consisting of configurations ranging from a few to dozens of communicating control nodes. The work confirmed the ability to deliver similar functional characteristics as centralized systems but in a distributed implementation. Performance testing and development verified sufficient performance and software life-cycle benefits

    This paper presents an investigation into the implementation of reconfigurable industrial applications using the IEC 61499 standard. An architecture and design methodology is proposed to allow for the addition of reconfigurable elements to existing IEC 61499 applications. The commercially available NxtForte IEC 61499 platform was chosen for experiments. The notion of state resumption is discussed along with a corresponding application level implementation. Deficiencies of the standard for promoting reconfiguration are outlined and some extensions are then proposed to streamline the development of reconfigurable applications.

    Abstract [en]

    The complexity of modern industrial automation systems means that designing with change in mind is a necessity. Event-driven and time-driven programming paradigms each have their own benefits for the development of distributed systems control. However, flexibility and reconfiguration will always be required as new technologies are introduced and increased distribution results in greater chances for point failures. Dynamic runtime based reconfiguration is desired to reduce any experienced downtime. Implementation of reconfiguration is problematic, particularly as the system grows in size. System behavior arises from complex interactions between distributed modules, making their reconfiguration inherently difficult. This paper proposes the unification of time-driven and event-driven control paradigms for the purpose of unification. A formal model discussing the suitability of this architecture for reconfiguration purposes is introduced. Each reconfiguration mechanism for the architecture and design patterns is then implemented in the IEC 61499 function block standard.

Both were deployed to hardware to demonstrate seamless testing using a single underlying architecture. A visualization of the simulation model was created to view the simulation live. Comparisons between IEC 61499 and traditional techniques were outlined during the implementation. Difficulties in applying commonly used traditional design elements to the IEC 61499 standard were addressed

    Cyber-Physical Engineering of Distributed Automation Systems in Energy Domain2018Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The main focus of this thesis is in the domain of Energy Systems, specifically in the engi-neering of modern Smart Grid (SG) automation systems. The SG has been categorizedas a Cyber-Physical System (CPS), a complex system which exhibits tight integration between the cyber and the physical processes and their interactions in a networked envi-ronment. The complexity and the computation of the automation system are expectedto increase with the promise of a ”smart” electric grid which is capable of self-healing, self-reconfiguration and become more resilient against cyber-attacks. These automation software systems require control strategies which are distributed in execution and requirevery tight integrations and interactions between various modular software and hardware components. As the automation system becomes more software intensive, we hypothesizethat existing design practices of developing the substation automation software system would struggle to cope with the distributed design challenges of the Smart Grid and they could be substantially enhanced by the application of model-driven design, distributed software architectures and semantic models.

    Model-driven engineering (MDE) is a software design paradigm that leverages the use of abstraction models at different stages of the design process for engineering complex software systems. MDE is widely used in the software engineering domain and it has proven to be effective when designing and maintaining large-scale software applications.One of the core tenants of MDE is model transformation and it is considered the heartand soul of MDE. The standard modelling language that is used for MDE in software engineering is the Unified Modelling Language (UML), which is a visual language with awide array of tool support. Despite its popularity in the software domain, UML models still have its limitations. In particular, the lack of uniformed semantics between its 13different visual diagrams and the lack of formal notations. In this thesis, we proposethe Cyber-Physical Engineering (CPE) framework, an MDE framework which combines semantic models and MDE based automatic model transformation in order to auto-generate both the automation control system and the simulation plant model from thephysical and functional specifications of CPS systems.

    All the scientific papers included in this thesis contributes towards the proposed Cyber-Physical Engineering methodology which includes MDE using semantic models, formal modelling of functional requirements and co-simulation testing of CPS systems.

    The contribution of the thesis is fivefold. Firstly, the thesis proposes the CPE frame-work, which is based on the use of semantic web modelling language where logical rea-soning can be applied to the models. The modelling language that is used is the Web Ontology Language (OWL), which is a declarative language with a strong formal foun-dation based on description logic. Secondly, the extended Semantic Web Rule Language(eSWRL) is introduced which defines the constructors that are necessary for model trans-forming OWL ontology models. The eSWRL transformation language is proposed to bean extension to the widely used ontology reasoning language Semantic Web Rule Lan-guage (SWRL) in order to address the limitations of monotonicity which restricts SWRLfrom transforming ontological models. Thirdly, the implementation of the underlying transformation engine of eSWRL in SWI Prolog. Fourthly, the formal modelling of func-tional requirements in ontology is proposed which investigates the viability of using nat-ural language based functional requirements to add control flow to the auto-generated automation control system. Lastly, an automated script based co-simulation environ-ment is shown to demonstrate how black-box validation can be performed to test theauto-generated automation control system.

    Finally, the thesis presents the resultant CPE framework for the modelling and genera-tion of distributed CPS automation software that leverages the use of semantic web OWL models. It is aimed to provide a top-down design approach of developing distributed con-trol software for CPS systems along with the simulation model of the physical plant. Inthis thesis, we demonstrate the development process of the CPE framework and throughcase study applications, how a semi-complete distributed automation software system in IEC 61499 can be automatically generated from substation specifications in IEC 61850 and natural language based functional requirements which provide the structure and thecontrol flow of the distributed automation software respectively. An eSWRL toolchainhas been developed to facilitate the various model transformation process of the CPE framework.

    Ontology Driven Approach to Generate Distributed Automation Control from Substation Automation Design2017Ingår i: IEEE Transactions on Industrial Informatics, ISSN 1551-3203, E-ISSN 1941-0050, Vol. 13, nr 2, s. 668-679, artikel-id 7762918Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper proposes a method for the automatic generation of smart-grid automation systems software from specifications that includes physical system layout and domain-specific functional “recipes.” The generated software has component organization and implements a decentralized approach to smart grid control, which reduces complexity of automation systems design and modification. The proposed method relies on synergies of two industrial standards IEC 61850 and IEC 61499, which are used to represent a part of the specification and the resulting software model, respectively. Then, the specification model is created in a form of ontology and the generation is based on ontology transformation. The proposed method requires an extension to the Semantic Web Rule Language (SWRL) to support the change of an ontology axioms set for the purpose of ontology transformation. The proposed transformation language, called extended SWRL, is introduced and illustrated in use. The result shows the viability of eSWRL as an ontology transformation language when demonstrated in a power distribution case study system.

    Automatic Generation of Control Flow from Requirements for Distributed Smart Grid Automation Control2019Ingår i: IEEE Transactions on Industrial Informatics, ISSN 1551-3203, E-ISSN 1941-0050Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Smart grid is a Cyber-Physical System with a high level of complexity due to its de-centralized infrastructure. IEC 61850 and IEC 61499 are two industrial standards which can address the challenges introduced by the Smart Grid on the substation automation level. Development of Smart Grid automation software is very time consuming process due to the need to address many requirements and high degree of customisation in every new substation. This limits the adoption of such smart grid technologies as digital substation. This paper aims at addressing this limitation by applying a semi-formal boilerplates model of functional requirements originally presented in informal natural language. The boilerplates are then modelled formally in an ontology for MDE model transformation. The contribution of this paper is the development of the semi-formal and formal boilerplate representation in the form of ontology to formulate Smart Grid requirements and demonstrating how functional requirements can be translated to IEC 61499 control codes using MDE to auto-generate an IEC 61499 PAC control system with structure and control flow. The MDE framework augmented with the requirements models is illustrated on a case study from CIGRE representing different stages of modelling in the proposed framework.

    Abstract [en]

    The investment to DERs (Distributed Energy Resources) in the emerging smart energy grids are critical to achieving goals for environmental protection, reducing energy costs and coping with failures. An architecture and market mechanism is needed to support the participation of owners of DERs that aim to maximize the profit from this investment within a system that is also able to achieve grid level objectives. Due to privacy requirements, owners of DERs should not be requested to divulge information such as the state of charge of a local energy store, and yet such information is very relevant for operating the grid in such a way that meets the objectives of the owner of the grid, who may operate a large power plant that is ultimately responsible for satisfying the load that cannot be covered by DERs. This paper builds on previous work to propose a modular multi-agent architecture in which prosumer agents represent DER owners and an auctioneer agent represents the power plant operator. The architecture allows the different agents to use different algorithms aiming at satisfying local and grid level objectives while meeting the privacy requirement. In particular, a fuzzy logic based algorithm is developed for the distributed automation platform that supports the architecture. The capability of the architecture to flexibly evaluate the performance of various algorithms from the DER owner and plant operator perspective is demonstrated with a case study in the district heating domain.

    Vehicle and pedestrian aware street lighting automation2015Ingår i: IEEE 13th International Conference on Industrial Informatics (INDIN), 2015: Cambridge, United Kingdom, 22-24 July 2015, Piscataway, NJ: IEEE Communications Society, 2015, s. 1269-1274, artikel-id 7281917Konferensbidrag (Refereegranskat)
    Abstract [en]

    The emergence of LED luminaires that can be dimmed rapidly and frequently enables radical innovations in street lighting automation. It is possible to save considerable amounts of energy by adjusting street lighting according to the movements of individual road users. Since the same lights are often used for illuminating both vehicle lanes and sidewalks, it is necessary to detect both vehicles and pedestrians. A simulation of vehicle and pedestrian traffic is interfaced to a distributed street lighting system based on the IEC 61499 standard, in order to quantify the energy saving potential of a street lighting automation system that exploits real-time sensing information of individual road users while conforming to traffic safety related requirements for road lighting

    Abstract [en]

    The future distribution grid known as the smart grid will become more distributed in both infrastructure and control. IEC 61850 and IEC 61499 are two industrial standards addressing the challenges presented by a decentralized infrastructure. This paper contributes to system engineering of smart grid automation by enabling automatic generation of IEC 61499 control systems from IEC 61850 specifications. The areas which this paper fills is proposing a method to formally capture the logical node to logical node message passing which is lacking in the IEC 61850 standard. The proposed method is to represent an IEC 61850 protection scheme as a graph and then integrate it into the IEC 61850 ontology developed previously. The case study used is a sympathetic tripping protection scenario which demonstrates how the process of developing the graph model from the protection scheme and applying ontology rules to automatically generate the resultant IEC 61499 function blocks with meaningful connections between the logical nodes.

    On requirements-driven design of distributed smart grid automation control2017Ingår i: Proceedings: 2017 IEEE 15th International Conference on Industrial Informatics, INDIN 2017, Piscataway, NJ: Institute of Electrical and Electronics Engineers (IEEE), 2017, s. 738-745, artikel-id 8104864Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper proposes a novel method of modelling requirements for smart grid automation systems that fits and complements the leading standards used for software development in smart grid: IEC 61850 and IEC 61499. Ontological representation is used to formally model the systems requirements and the integration of the requirement modelling to be used in conjunction with IEC 61850 specifications and IEC 61499 implementation. The proposed model is illustrated on a case study presented by the CIGRE working group where the system requirement in natural language was firstly modelled in ontology, then implemented in IEC 61499. Lastly, the resulting IEC 61499 control system was tested and validated against the system requirement by signal testing of the end control system.

    Abstract [en]

    In this paper, the aim of automatically generating a cyber-physical control system (more precisely, an IEC61499 control system) is discussed. The method is enabled by ontology models, specifically the source plant ontology model and the target control model for the CPS system implemented in the preferred programming language. The transforming of ontologies is enabled by an extension of SWRL (called eSWRL) and it is introduced here. There interpreter of eSWRL is developed using the Prolog language. A case study Baggage Handling System is used to demonstrate how the ontology models are transformed and the corresponding transforming rules that are developed

    On development of execution model for model transforming distributed substation automation control with ontology2017Ingår i: 2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), Piscataway, NJ: Institute of Electrical and Electronics Engineers (IEEE), 2017, s. 1219-1225, artikel-id 8001419Konferensbidrag (Refereegranskat)
    Abstract [en]

    The so called Smart Grid is said to be enabled with bi-direction communication networks and energy flow. IEC 61850 is a substation communication standard which improves interoperability of the substation design. IEC 61499 is an automation standard which can be used for implementation of control in IEC 61850 models. This work is utilizing Model Driven Engineering techniques for substation automation systems, specifically using ontology models to automatically generate IEC 61499 distributed automation control systems. eSWRL is the proposed ontology transformation and it is necessary to develop an execution model for executing the transformation rules. This paper explores the use of several execution semantic models for eSWRL and illustrates the use of the most suitable execution model for the context of this work. In the case study, eSWRL rules are written using the execution models discussed in this paper to generate a distributed automation control library in IEC 61499.

    On Automatic Generation of IEC61850/IEC61499 Substation Automation Systems Enabled by Ontology2015Ingår i: IECON 2014: 40th Annual Conference of the IEEE Industrial Electronics Society, Dallas, TX, USA , Oct. 29 2014 - Nov. 1 2014, Piscataway, NJ: IEEE Communications Society, 2015, s. 3577-3583Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents an introductory step in theautomatic generation of distributed control software for powerdistribution automation systems based on Ontology DrivenEngineering enabled by industrial standards IEC61850 andIEC61499. The novelty of this approach is the ability ofautomatically generating the logical connections between thelogical nodes. The paper covers the several stages of thetransformation process, such as developing the IEC61850ontology and the ontology transformation rules. The developed IEC61850 ontology includes the logical nodes descriptions and additional contextual relations between the logical nodes which is lacking in the IEC61850 SCL configuration language. Then, the IEC61850 ontology is transformed to an existing IEC61499 ontology, adding classes of IEC61850 logical nodes as IEC61499 function blocks in the IEC61499 ontology. The means of the transformation of the ontologies is based on the eSWRL sematic web rules language, an extension to the rule language SWRL. The end result is the development of an IEC61850 ontology and a set of eSWRL rules which facilitates the ontology transformation.

    Programmable Logic for IEC 61850 Logical Nodes by means of IEC 614992011Ingår i: IECON 2011: 37th Annual Conference on IEEE Industrial Electronics Society : Melbourne, VIC; 7 November 2011 - 10 November 2011, Piscataway, NJ: IEEE Communications Society, 2011, s. 2717-2723Konferensbidrag (Refereegranskat)
    Abstract [en]

    IEC61850 is a recent standard in substation automation system (SAS) aiming mainly at interoperability. Interoperability is achieved by standardizing communications and data between intelligent electronic devices (IEDs). Data inintelligent electronic devices are modelled in IEC61850 using an object orientated approach as logical nodes. Although the IEC61850 standardizes the data and communication in substation design, the implementation of control is intentionally left out of the standard. IEC61499 function blocks has been proposed tofill the logic void of the IEC61850 standard. In this paper, intelligent logical node (iLN) architecture is used, which combines both description and control within IEC61850 logical nodes. An IEC61850 application presented at the IEC TC57WG10 has been modelled using the iLN architecture with the addition of editable logics within the iLN architecture by means of IEC61499 function blocks implemented in the ISaGRAF development platform.

    Towards Implementation of IEC 61850 GOOSE Messaging in Event-Driven IEC 61499 Environment2014Ingår i: Proceedings of 2014 IEEE 19th International Conference on Emerging Technologies & Factory Automation (ETFA 2014): Barcelona, Spain, 16-19 Sept. 2014, Piscataway, NJ: IEEE Communications Society, 2014, s. 464-470, artikel-id 7005253Konferensbidrag (Refereegranskat)
    Abstract [en]

    IEC 61850 is a new standard for substation automation which attempts to standardize communication within substations by introducing a set of new communication services operating over the Ethernet framework. The communication of interest for protection is IEC 61850 GOOSE messaging. GOOSE messaging is a peer to peer service designed for protection applications within substations. There is a growing interest in filling the void of control in the IEC 61850 standard. The Intelligent Logical Nodes (iLN) architecture is one such solution which uses IEC 61499 as the complimentary control system for IEC 61850. The missing component in the iLN architecture is the various communication profiles introduced in the IEC 61850 standard. This paper presents an implementation of IEC 61850 GOOSE messaging for the IEC 61499 IDE that implements event-driven execution semantics by means of the SharpPcap library.

    Towards implementation of Plug-and-Play and distributed HMI for the FREEDM system with IEC 614992013Ingår i: IECON 2013: 39th Annual Conference of the IEEE Industrial Electronics Society, Piscataway, NJ: IEEE Communications Society, 2013, s. 5347-5353Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents an implementation of Plug-and-Play for the FREEDM system with IEC61499 function blocks. The FREEDM system is the envisioned next generation power distribution infrastructure which integrates DRER/ER with the legacy grid and is enabled by novel power electronics and distributed control. Plug-and-Play device integration is one of the key features of the FREEDM system that allows distributed renewable energy resources and distributed energy storage devices to be added or removed from the FREEDM distributed intelligent devices seamlessly. IEC61499 is an open standard for designing distributed control systems, which is investigated in the FREEDM project as an underlying system-level software architecture. Plug-and-Play is achieved by dynamic reconfiguration in IEC61499 to create the necessary function blocks during runtime for enabling Plug-and-Play between the DRER and the DGI devices. The developed Plug-and-Play technology is incorporated into the FREEDM infrastructure implemented in IEC61499

    Smart grid automation: Distributed protection application with IEC61850/IEC614992013Ingår i: IEEE 10th International Conference on Industrial Informatics: 25-27 July, 2012, Beijing, China., Piscataway, NJ: IEEE Communications Society, 2013, s. 1067-1072Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper proposes solutions for distributed protection applications, to improve current and design of future protection schemes. This solution utilises advantages of fast and reliable peer-to-peer communication of IEC 61850 and interoperability and configurability of IEC 61499. The integration of the two standards improves protection schemes by decreasing fault clearing times and minimizes the effect of short circuit faults on sensitive loads. Additional advantages include the reductions of the number of hard-wired connections, especially in a large substation where all protection IEDs has a significant number of binary inputs and relay outputs. IEC 61499 is an open standard for designing distributed control systems to promote portability, interoperability and configurability, i.e. vendor independent, flexible and robust solutions. IEC 61499 can be used to represent programmable logic of power system devices, in a standard form and in a vendor independent way. The proposed distributed protection system is implemented and simulated using the developed co-simulation environment.
