Single-Phase PQ Inverter Model and Application to Unbalance Compensation in Islanded Microgrids (PSCAD Simulation)

Abstract

This is a simulation study of islanded microgrids for black start purpose. The study focuses on the voltage unbalance that results from serving unbalanced loads in the distribution system and how this could be mitigated by the use of three-phase stacked single-phase PQ inverters. Simulation is performed in PSCAD/EMTDC software and the files have been freely made available. Full model and the voltage-controlled source model of the single-phase PQ inverters were developed and incorporated into the case studies.
