Power Exchange Control of Clusters of Multiple AC and DC Microgrids Interconnected by UIPC in Hybrid Microgrids

Abstract

This work accentuates on using unified interphase power controller (UIPC) to control power flow between clusters of multiple microgrids in a hybrid microgrid. The clusters of microgrids are interconnected through the UIPC, which is able to provide bidirectional power flow between the clusters. A new optimal fractional order-based control strategy is described for UIPC control. Simulation results are provided for power exchange control performance between clusters of AC and DC microgrids as well as with the main power grid.
