Document Type and Number:
WIPO Patent Application WO/2018/056504
Kind Code:
A1
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.
