SYSTEM AND METHOD FOR FUZZY DROOP CONTROL OF MULTI-BESS IN MICROGRID

摘要

The present invention relates to a microgrid. More particularly, the present invention relates to a fuzzy droop control technique. Based on the frequency of the microgrid, the frequency of the micro grid is kept within an allowable range according to power outputted from multiple distributed power sources. In order for frequency droop control for outputting power, the output of battery energy storage system (BESS) is changed by changing a droop gain in consideration of the state of charge (SOC) of a battery of the BESS and battery capacity together. The SOC of the battery can be efficiently managed.;COPYRIGHT KIPO 2017
