Title of Experiment

Hardware-in-the-Loop for inverter controller validation in real conditions

Research Infrastructure

Electric Energy Systems (ICCS-NTUA)

Experiment Realisation

Multiple inverters forming a microgrid, both through hardware setup and through simulated components in the RTDS

Experiment Setup (concrete lab equipment)
  1. Real Time Digital Simulator (RTDS)
  2. PC for RSCAD (UI of RTDS)
  3. Hardware controller (Triphase)
  4. Interfacing I/O cards
Experimental Design and Justification
  • In RSCAD an inverter-based microgrid will be designed. The inverters will be simulated as controlled voltage sources to facilitate testing of the control scheme under faults.
  • FRT curve according to Grid Codes, will be used.
  • A hardware controller will be connected to RTDS to perform CHIL experiments and validate the control algorithm under real conditions.
Precision of equipment and measurement uncertainty
