Method for controlling frequency of stand-alone microgrid and power converter for energy storage device for controlling same

Last updated:

Abstract:

The present invention relates to a method for controlling the frequency of a stand-alone microgrid wherein an energy storage device of the stand-alone microgrid is operated as a main power source by controlling a battery power conditioning system (PCS) of the stand-alone microgrid in a constant voltage constant frequency (CVCF) mode. According to the present invention, it is possible to operate the frequency stably while considering the fuel cost and power generation efficiency of a stand-alone microgrid.
