  1. SYSLAB A platform for research and testing of decentralised energy resource based power systems Henrik Bindner Wind Energy Systems Wind Energy Division Risø DTU Vind i Øresund Kick-off møde, LTH, december 2008 Acknowledgement: The parts of the work presented is supported by EnMi-project ” Self-organising distributed control of a distributed energy system with a high penetration of renewable energy” and ForskEl-project ”Characterisation of Vanadium Batteries”

  2. SYSLAB – Distributed Energy System Laboratory • SYSLAB is a platform for Decentralised Energy Resources research and testing • It is a flexible experimental setup up • It includes several production and consumption units • It has embedded computing power and flexible communication • It has very flexible control possibilities • It can be extended 11kW 7kW 48kW/60kVA 13*1kW 55kW 15kW/120kWh 9kWh

  3. Main parts of SYSLAB • Production and consumption equipment • Measurement system • Computer network • Node-computers with linux • Software: agent platform, measurement database

  4. Electrical layout of SYSLAB • Flexible grid configuration • Autonomous grid • Units can be tested in under various grid conditions • Suitable for component as well as system tests • Very flexible control • Control computer at each component • Communication network • Agent-based software infrastructure

  5. Execution platform • Interactions between entities defined in software, not hardware • easier transition between the current system (static hierarchy)‏and future paradigms, as research progresses

  6. What can SYSLAB be used for • System control concepts • Distributed and decentralised control • Exploitation of demand response/demand side management • Communication – what has to be communicated, what happens when the communication is interrupted • Interaction between components in a heterogenoues system • Wind, Solar, Electrochemical Storage, Hydrogen system, Conventional production, Loads etc. • Testing of components • Characterisation • System properties

  7. Examples on activities in SYSLAB • System Control: • Self-organising distributed control of a distributed energy system with a high penetration of renewable energy (EnMi) • Energy Storage: • Characterisation of Vanadium redox-flow batteries (PSO) • Flexible Consumption: • FlexHouse

  8. Self-organised distributed control of a distributed energy system with a high penetration of renewable energy • Activation of distributed resources • Utilisation of local resources • Seamless integration with system control (plug and play) • System is able to handle new components as well as new configurations e.g. caused by faults • Agent-based control of power system • Agents are software objects that are • Connected to the real world • Pursuing a goal • Interacting with other agents

  9. Vanadium battery at SYSLAB • AC power: ±15 kW • Storage: 120 kWh • Battery system includes: • Cell stacks (340 cells in total) • Electrolyte and storage (26500liter) • Balance of plant (pump, pipes, etc.) • Control and communication unit • Four quadrant AC/DC power converter • Total price: 750.000 DKK

  10. Power Converter efficiency ~85% Auxilliary Power Consumption ~1.4kW (almost constant) Cell stack efficiency high Converter losses are high Auxilliary power consumption is relatively high Round trip efficiency : electricity → storage → electricity Cell stack (DC power) Cell stack and power converter (AC) Total, including auxiliary power and storage losses

  11. Provide a software and hardware platform for implementation of controllers for flexible consumption Study control strategies for flexible loads, sensor requirements, modelling Investigate how users can interact with system Enable investigation of the interaction between control capabilities of a consumer load and the requirements of the rest of the system Communication interface between load and system: Which information to exchange, How to communicate strategies, Links to existing communication protocols Power FlexHouse

  12. RE in transport Coordination control of charging/discharging to support grid Intelligent control Driving patterns Forecasting techniques for charging decisions Charging depending on grid state Extended battery 9kWh LiFePO4 (48*24 cells) 1kW charging power 50km range as EV Future Vehicle2grid hybrid car: Bi-directional converter Support grid Plug-in Hybrid Cars/Electric Vehicles

  13. Integrates several areas of research Upscaling to nationwide system Simulations (IPSYS) Facility used in PhD and MSc projects SYSLAB is part of Powerlab.dk Investigate technical possibilities Embedded intelligence Distributed/Decentralised control Integration of energy carriers Multiple RE sources Possible extensions Hydrogen/Fuel cells Biomass Risø district heating/houses 1-5 kW Topsoe FC CHP Test System SYSLAB – Development perspectives
