Frequency Spectrum Based Coordinate Control Scheme for Several Types of Distributed Power Generation Systems in a Micro Grid

A power control method to compensate power fluctuation of the load in the micro grid systems is proposed and discussed. Active power responses of several kinds of distributed power generation systems (DGs) such as gas engine, micro gas turbine etc., energy storage system, and load fluctuation of a site have been measured. Based on the measurements, coordinate control system for several kinds of DGs has been constructed. Simulation and experiments have been carried out with small-scale micro grid model system. It is shown that the load fluctuation has been compensated by the proposed method
