Power Hardware-in-the-Loop (PHIL) simulation environment

Power Hardware in the Loop (PHIL) simulation is a very promising approach for simulating and testing of DER devices, available in only a few facilities world-wide. The PHIL facility developed at NTUA provides an efficient environment for studying interactions between hardware DER power devices and various simulated networks. A rack of the commercially available Real Time Digital Simulator RTDS® is operated. In dedicated software electric power networks with various components such as generators, transformers, protection devices, loads, distributed generation etc. are simulated with a typical time-step of 50 usec. A Switched-Mode Amplifier provided by Triphase is used as a Power Interface between the RTDS and physical equipment to perform PHIL simulation. The power electronic converter platform allows the user to design a Matlab/Simulink control model, upload it to the Target PC (converter’s powerful control unit) and connect the user’s PC to the Target PC to allow real-time control of and interaction with the inverter cabinet.


PHIL experiments are performed, where hardware photovoltaic (PV) panels and a PV inverter are connected to simulated distribution networks. An irradiation sensor provides input to simulated PVs in the RTDS in order to achieve realistic conditions. The connection of the whole microgrid and the Multi-Agent System to the PHIL environment is in progress.
