    PROSA/G: An architecture for agent-based manufacturing execution2018Ingår i: 2018 IEEE 23RD INTERNATIONAL CONFERENCE ON EMERGING TECHNOLOGIES AND FACTORY AUTOMATION (ETFA), Piscataway, NJ: IEEE, 2018, s. 155-160Konferensbidrag (Refereegranskat)
    Abstract [en]

    It had always been the intention of the agent-based manufacturing community that software agents would provide a vertical integration capability for manufacturing enterprises by linking the control world with the business world. In this paper, we introduce the PROSA/G conceptual model, which extends the widely used PROSA reference architecture with a goal-based execution model that employs both BDI semantics and a business process modelling metaphor. PROSA/G is is grounded in the GORITE software framework and its efficacy is demonstrated through the implementation of an agent-based execution system for a simple manufacturing system controlled by IEC 61499 function blocks.

    Towards a formal model of protection functions for power distribution networks2016Ingår i: ECON Proceedings (Industrial Electronics Conference), Piscataway, NJ: IEEE Computer Society, 2016, s. 5302-5309, artikel-id 7794150Konferensbidrag (Refereegranskat)
    Abstract [en]

    The protection system is a crucial part of the power grid. It protects people, equipment, and property. Reliability of such mission critical systems is of an extreme importance. Protection systems have strict requirements to reliability including dependability, security and timeliness. Although it undertakes rigorous testing and commissioning, it fails in some circumstances causing faults in the network, resulting in loss of power. It is hard to catch these hidden and undetectable errors in the design and installation. Since protection function is essentially a piece of code, formal methods can be used for rigorous testing of the software and provide definitive proof of the system properties. This paper proposes a formal model (to use in formal verification techniques) for protection systems. The paper develops closed loop model of the electrical network with its protection system. The model is developed in IEC 61499 language for the further generation of its formal model in SMV language. The model is validated via simulation and comparison with a comprehensive model of the electrical network in Matlab Simulink. In future work, the generated SMV model will be used to formally verify reliability requirements of the protection system.

    TORUS: Scalable Requirements Traceability for Large-Scale Cyber-Physical Systems2019Ingår i: ACM transactions on cyber-physicals systems, ISSN 2378-962X, Vol. 3, nr 2, artikel-id 15Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Cyber-Physical Systems (CPS) contain intertwined and distributed software, hardware, and physical components to control complex physical processes. They find wide application in industrial systems, such as smart grid protection systems, which face increasingly complex communication and computation needs. Due to the scale and complexity of the interactions that occur within CPS, tracing requirements through to the system components and software code that implement them is often hard. Existing requirements management systems do not scale well, and traceability is difficult to implement and maintain in highly heterogeneous systems. However, the information trace that links provide is crucial for supporting testing and certification activities in safety-critical environments such as smart grids.

    The well-formed models of power systems provided by the IEC 61850 standard and the software design structure provided by the IEC 61499 Function Blocks standard can be leveraged to automate many traceability operations. We present Traceability of Requirements Using Splices (TORUS), a novel traceability framework for the development of large-scale safety-critical CPS. TORUS introduces splices, autonomous graph-based data structures that automatically create and manage trace links between requirements and components through the inevitable changes that occur during system development. The formal, graph-based structure of TORUS lends itself well to the development of sophisticated algorithms to automate the extraction of useful traceability information such as historical records and metrics for requirements coverage and component coupling. By capturing not only the current state of the system but also historical information, TORUS allows project teams to see a much richer view of the system and its artifacts.

    We apply TORUS to the development of a protection system for smart grid substations. In addition, through a number of experiments in splice creation, modification, and application of automated algorithms, we show that TORUS scales easily to large systems containing hundreds of thousands of requirements and system components and millions of possible trace links.

    A Review of Architectures and Concepts for Intelligence in Future Electric Energy Systems2015Ingår i: IEEE transactions on industrial electronics (1982. Print), ISSN 0278-0046, E-ISSN 1557-9948, Vol. 62, nr 4, s. 2424-2438Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Renewable energy sources are one key enabler to decrease greenhouse gas emissions and to cope with the anthropogenic climate change. Their intermittent behavior and limited storage capabilities present a new challenge to power system operators to maintain power quality and reliability. Additional technical complexity arises from the large number of small distributed generation units and their allocation within the power system. Market liberalization and changing regulatory framework lead to additional organizational complexity. As a result, the design and operation of the future electric energy system have to be redefined. Sophisticated information and communication architectures, automation concepts, and control approaches are necessary in order to manage the higher complexity of so-called smart grids. This paper provides an overview of the state of the art and recent developments enabling higher intelligence in future smart grids. The integration of renewable sources and storage systems into the power grids is analyzed. Energy management and demand response methods and important automation paradigms and domain standards are also reviewed

    Abstract [en]

    The intention of this paper is to provide an overview of using agent and service-oriented technologies in intelligent energy systems. It focuses mainly on ongoing research and development activities related to smart grids. Key challenges as a result of the massive deployment of distributed energy resources are discussed, such as aggregation, supply-demand balancing, electricity markets, as well as fault handling and diagnostics. Concepts and technologies like multiagent systems or service-oriented architectures are able to deal with future requirements supporting a flexible, intelligent, and active power grid management. This work monitors major achievements in the field and provides a brief overview of large-scale smart grid projects using agent and service-oriented principles. In addition, future trends in the digitalization of power grids are discussed covering the deployment of resource constrained devices and appropriate communication protocols. The employment of ontologies ensuring semantic interoperability as well as the improvement of security issues related to smart grids is also discussed.

    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.

    Cosimulation environment for event-driven distributed controls of smart grid2013Ingår i: IEEE Transactions on Industrial Informatics, ISSN 1551-3203, E-ISSN 1941-0050, Vol. 9, nr 3, s. 1423-1435Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper proposes a co-simulation environment for “hardware in the loop” or “software in the loop” validation of distributed controls in Smart Grid. The controls are designed using model-driven engineering with the IEC 61499 Function Block architecture. These are connected with plant models, for example in MATLAB/Simulink, through communication channels such as UDP or TCP sockets. This solution enables multi-closed-loop plant-controller simulation. The communication between plant and controller is event-driven. In order to perform realistic simulation, the proposed solution takes into account computation and communication delays on the controller side in Function Blocks and compensates model time on the plant side in MATLAB model accordingly. Causality and accuracy of the method have been formally addressed. This approach has been tested and demonstrated with several Smart Grid-related examples.

    A Comprehensive Model of Data Center: from CPU to Cooling Tower2018Ingår i: IEEE Access, E-ISSN 2169-3536, Vol. 6, s. 2169-3536Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aiming at addressing environmental challenges, large data centers such as Facebook, Google, Yahoo, etc., are increasing share of green power in their daily energy consumption. Such trends drive research into new directions, e.g. sustainable data centers. The research often relies on expressive models that provides sufficient details however practical to re-use and expand. There is a lack of available data center models that capture internal operating states of the facility from the CPU to the cooling tower. It is a challenge to develop a model that allows to describe complete data center of any scale including its connection to the grid. This paper proposes such a model building on existing work. The challenge was to put the pieces of data center together and model behavior of each element so that interdependencies between components and parameters and operating states are captured correctly and in sufficient details. The proposed model was used in the project “Data center microgrid integration” and proven to be adequate and important to support such study.

    Abstract [en]

    This paper proposes an agent-oriented design methodology specific to power system automation domain. The existing agent-oriented methodologies have some deficiencies when applied in industrial automation. Besides, there is lack of models, methods and guidelines for their systematic application. The proposed methodology combines familiar to domain engineer design process of the IEC 61850 standard and design flow of agent-oriented methodologies. The resultant agent-based system is modelled and implemented with IEC 61499. The transformation of IEC 61850 models into the IEC 61499 solution models is guided by the set of rules and supported by automated transformation tool. The methodology has a set of models, their transformation methods and well defined steps that enable systematic design of the agent-based solutions for power system. The methodology is exemplified here on a Smart Grid protection application

    Towards software metrics for evaluating quality of IEC 61499 automation software2015Ingår i: Proceedings of 2015 IEEE 20th International Conference on Emerging Technologies & Factory Automation (ETFA 2015): Luxembourg, 8-11 Sept. 2015, Piscataway, NJ: IEEE Communications Society, 2015, artikel-id 7301502Konferensbidrag (Refereegranskat)
    Abstract [en]

    The quality of the software has an increasing impact on the performance, operation and ultimately the cost of industrial automation systems. Software metrics are necessary to assess the quality and to identify modules that impact cost of testing and maintenance. There is a number of software metrics available within a software engineering domain. However, there is a gap when it comes to evaluating IEC 61499 automation software. It is a challenging task too. IEC 61499 architecture embraces several software development techniques such as imperative languages, state machines and object oriented programming. This paper proposes the method for calculating metrics for IEC 61499 function blocks. These metrics were used to analyze power system protection software. Metrics confirmed expected results and reasonably described quality of software modules. With further improvement and expansion of the proposed set of metrics, it will be possible to accurately analyze and therefore improve automation software design and reduce cost.

    Abstract [en]

    Agent technology in the power system domain isthe realm of theory and laboratory simulation. Agent-basedsystems, due to their complexity of concept and design, mayappear difficult to implement and maintain, and hence moreexpensive, which is a prohibiting factor against using the newtechnology. Designing a decision-making system for an agent isone of the most complex tasks in the development of agent-basedsystems. Designing a decision-making system enabling proactivebehaviours while maintaining reasonable complexity is achallenge. This paper proposes an deliberative decision makingsystem for an industrial agent which allows pro-active behaviourof the agent while maintaining reasonable complexity. It employsa combination of practical and procedural reasoning principles.The formal definition of the proposed deliberative layer isderived in the paper. The procedural reasoning is based on IEC61850 Logical Node concept and implemented with IEC 61499reference architecture. The proposed agent architecture isdemonstrated on the Fault Location Isolation and SupplyRestoration application and validated via so-simulation withMatlab model of the sample distribution network.

    Towards industrially usable agent technology for Smart Grid automation2015Ingår i: IEEE transactions on industrial electronics (1982. Print), ISSN 0278-0046, E-ISSN 1557-9948, Vol. 62, nr 4, s. 2629-2641Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This work is aimed at facilitating industrial adoption of agent technology. The paper proposes the hybrid agent architecture specific to the power system automation domain. The architecture builds on the Logical Node concept of IEC 61850 and comprises of a deliberative and a reactive layers; combining advantages of both. By relying on the underlined industrial standards IEC 61850 and IEC 61499, the architecture ensures practical applicability and captures domain specific concepts in the agent-based system design. Developed agentbased system was validated in the co-simulation framework. The architecture provides for rapid system development, reducing the software development life cycle. The benefits are in trace-ability of the software requirements, re-use of software components, ease of re-design, and direct deployment of the system model.

    Agent-based distributed consensus algorithm for decentralized economic dispatch in Smart Grid2013Ingår i: IECON 2013: 39th Annual Conference of the IEEE Industrial Electronics Society, Piscataway, NJ: IEEE Communications Society, 2013, s. 1968-1973Konferensbidrag (Refereegranskat)
    Abstract [en]

    The agent based solutions are successfully applied in research and have impressive results. However, at the present, the agent technology is the realm of theory and laboratory simulation. The paper presents an attempt to bridge the gap. To facilitate migration of agent technology to the field, we propose to apply industrial standards such as IEC 61499 to design and implement the agent based algorithms. IEC 61499 is reference architecture for development of distributed systems. As an example of agent based solution to power system problem we consider Incremental Cost Consensus (ICC) algorithm for solving economic dispatch problem. The original system was simulated in Matlab. The agent based 5 node system was developed using IEC 61499 and deployed to 5 industrial controllers, then tested. With the proposed approach the agent algorithms can be designed, tested and deployed within one framework without the overhead of re-coding the solution for different stages. The proposed approach enables directly executable agent solutions and paves the way to the industrial adoption of the agent technology in power system domain.

    Cyber-physical components for heterogeneous modeling, validation and implementation of smart grid intelligence2014Ingår i: 12th IEEE Conference on Industrial Informatics (INDIN 2014): Porto Alegre, Brazil, 27 - 30 July 2014, Piscataway, NJ: IEEE Communications Society, 2014, s. 411-417Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a practical framework to bring the cyber-physical block diagram models, such as Ptolemy, to the practice of industrial automation. Cyber-Physical Component (CPC) architecture is suggested. CPC aims at the improvement of design, verification and validation practices in automation of Smart Grid. IEC 61499 standard is used as a basis for this architecture. This architecture addresses several design software and system engineering challenges: right equilibrium between abstract representation and “executability” and round-trip engineering. An CPC exhibit such properties as portability, interoperability and configurability thanks to the reliance on open standards. The use of time stamp based execution paradigm adds determinism and predictability at the run-time.

    SysGrid: IEC 61850/IEC 61499 based engineering process for Smart Grid automation design2013Ingår i: 11th IEEE International Conference on Industrial Informatics, INDIN 2013: Bochum, Germany 29 July - 31 July 2013, Piscataway, NJ: IEEE Communications Society, 2013, s. 364-369Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper proposes a novel computer-aided model-based system engineering process for Smart Gird applications. The process is supported by the SysGrid tool that plays the roles of system configurator and device configurator. The design process starts with single line diagrams which are automatically transformed to executable function block specifications. The process is based on the Smart Grid control architecture that is a heterogeneous network of controllers communicating in a peer to peer manner. This “artificial nervous system” of the Smart Grid will be capable of self-healing and dynamic adaptation to renewable generation and ever-changing loads. The tool supports system-level design of automation logic in the form of function block networks with compliancy to IEC 61499. The capabilities of SysGrid are demonstrated through the process of designing a distributed protection application.

    Open Architecture for Cost Effective Protection and Control of Power Distribution Networks2016Ingår i: IEEE International Conference on Smart Grid Communications (SmartGridComm) 2016, Piscataway, NJ, 2016, s. 729-735, artikel-id 7778848Konferensbidrag (Refereegranskat)
    Abstract [en]

    The paper aims at demonstrating the feasibility of an execution platform that is capable of performing protection and control functions from various vendors in a controlled manner. This will reduce vendor dependency enabling utilities to standardize hardware while implementing complex protection schemes from multiple vendors at reduced cost. The paper develops protection system including earth, differential and overcurrent protection functions from different vendors integrated in one hardware using IEC 61499 open reference architecture. IEC 61499 enables efficient and flexible design and implementation of the distributed automation systems. Selected substation is modelled in Matlab Simulink. Developed protection scheme is performed by programmable automation controller (PAC) and validated by connecting it to the simulation model of the substation. The protection scheme satisfied all functional requirements. At present, authors are working on validating its timing properties.

    Data center energy efficiency and power quality: An alternative approach with solid state transformer2016Ingår i: Annual Conference of the IEEE Industrial Electronics Society, IECON 2015: Yokohama, Japan, 9-12 Nov. 2015, Piscataway, NJ: IEEE Communications Society, 2016, s. 1294-1300, artikel-id 7392279Konferensbidrag (Refereegranskat)
    Abstract [en]

    Data center evolved to become large power consumers. Its supporting infrastructure, such as cooling and power distribution, consumes resources e.g. electric power and money. In fact, most money is spent on power conditioning and cooling systems. Therefore, the efficiency of data center and power quality are important topics and can be addressed by careful design. There is a need for research into application of innovative design and state-of-the-art technology for optimizing power supply in data centers. The paper investigates potential of a state-of-the-art technology such as solid state transformer (SST). The simulation proves that SST has potential to improve operational efficiency. SST shows better control of voltage, current and reactive power of the facility, eliminating need for additional devices such as power conditioners and reducing power loss. These results lead to the next stage of the project that involves developing an optimal data center design with SST and investigating data center potential in demand response applications.
