The Power Systems Testbed’s primary target is the increase of the penetration of Renewable Energy Sources (RES) to reduce greenhouse gas emissions. The testbed’s main activities involve the modelling, simulation, emulation, and experimental validation of energy systems. The Power Systems Testbed has high capabilities in developing smart converters for the integration of renewable energy sources both at the building and grid level, as well as in generation and storage technologies. Further capabilities include the development of real-time control algorithms for power electronic converters to advance the interconnection of renewable energy sources. ArchitectureThe key setups of the KIOS CoE power system testbed are summarized below: Real-time simulator and hardware in the loop (HIL) framework:The Real-Time Simulator is a core component of the Power Systems Testbed, allowing the development of digital twins of power systems based on accurate modeling and considering field measurements. It can be used to perform control-HIL studies and power-HIL investigations by considering the interaction between physical devices and digital twins. The real time simulator allows utilities, manufacturers, operators and research institutions to test multiple hardware devices and software solutions in a closed loop adjusting grid and network parameters, contingency scenarios, and device settings in a safe environment.
Fully programmable grid-connected inverter for photovoltaic-battery systems:A prototype three-phase grid-connected power electronics inverter (5kVA, 400V) can be used to enable the grid-friendly integration of photovoltaic and storage system. A high DC power supply is used as photovoltaic or battery emulator to create the primary source of energy. The inverter controller is fully programmable through a dSPACE control platform and setup can be used to test and demonstrate new functionalities and robust control and coordination schemes in renewable energy sources applications. Energy storage applications:Three main setups are available to examine and demonstrate novel functionalities enabled by energy storage systems. A flywheel-based energy storage system (6kWh, 10kW) is used to ensure grid friendly integration of photovoltaics and peak shaving applications in distribution grids. Two lithium ion battery storage systems (15kW - 15kWh and 5kW – 10 kWh) are used to demonstrate novel functionalities in different applications: grid-level storage (frequency reserve, peak-shaving, community battery, etc.), storage associate with renewable energy (track the day ahead prediction, compensate the uncertainties, ramp limiting, etc.) and building-level applications (intelligent self-consumption mode, voltage support, etc.). The innovative functionalities are integrated with all the prior-mentioned energy storage system through a cloud-based solution developed by KIOS CoE.
