Analysis of Fuzzy Inference Power Control Strategies for Islanding Operation of Microgrids

Microgrid is a latest notion for future energy distribution system that enables renewable energy integration. It generally consists of multiple distributed generators that are usually interfaced to the grid through power inverters. Fuzzy controller is proposed at Distributed Generation (DG) units for the islanding operation of ac microgrids. Two important jobs are to divide up the load demand among multiple parallel connected inverters proportionately, and maintain the voltage and frequency stabilities. Finally, this paper presents the deviation in power and frequency of micro grids with DG Units.
