    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.

    Abstract [en]

    Data centers have grown to become big energy cconsumers. At this scale of power consumption, data centers play cconsiderable role in electric networks operation. However, being ca relatively new industrial scale consumer, data center requires cmore careful consideration and research to uncover its specifics cand better understand its requirements; and investigate data ccenter's impact on regional grid. This paper reports on the work cin progress and at this stage details an effort to understand the cimpact of dynamic server load of a data center on its power cinfrastructure and further on the grid; the effects of transient cfaults in power grid on performance of a data center. This will chelp regional grid operators to improve power balancing within cthe network to maintaining network stability avoiding failures cand blackouts. The results of this work will be used in developing cdynamic power balancing strategy for a smart grid containing clarge data centers.

    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.

    Cooling Energy Consumption Investigation of Data Center IT Room with Vertical Placed Server2017Ingår i: Energy Procedia, ISSN 1876-6102, E-ISSN 1876-6102, Vol. 105, s. 2047-2052Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    As energy consumption by cooling data center IT equipment can be over 40% of total energy consumption, efficient cooling for large data centers is essential for reducing operation costs. Modern data centers are complex systems involving IT facilities, power system, cooling and ventilation systems. In our previous work, literature study was made to investigate available data center energy consumption models; and energy consumption models for data center IT room with distributed air flow control were developed. In this paper, the models are further extended and developed to cover the combined distributed air flow control and vertical placed servers in raised floor ventilation system. Simulation of the three types of ventilation systems with Even load, Idle server and Uneven load scenarios showed that significant cooling energy consumed by a traditional ventilation system can be saved by applying the proposed new concept and method.
