A Robust Controller Design for Standalone Microgrid System Feeding Composite Loads
Microgrid is one of the popular architectures to accommodate renewable-based distributed energy resources (DER’s). A microgrid may be operating in grid-tied mode or it may be in standalone mode feeding local loads of different natures. In this paper, design of a robust controller is presented for a standalone microgrid system which is feeding a composite load consisting of a linear load and a constant power-type load. Performance of standalone microgrid system with and without controller has been compared. Results are indicative that microgrid has stable operation with controller while feeding composite loads.
