Title:
PCS FOR ESS AND PCS OPERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/117530
Kind Code:
A1
Abstract:
According to the present invention, provided is a failure processing method for a microgrid including ESS, the microgrid comprising a plurality of distributed power sources, a plurality of distributed loads, lines connecting the distributed power sources and the distributed loads, and an ESS for storing power supplied from all or some of the distributed power sources and providing stored power to all or some of the distributed loads. The failure processing method can comprise the steps of: cutting-off the distributed power sources and a PCS for ESS in charge of the ESS when a microgrid system detects a failure; connecting the PCS for ESS to the microgrid; determining a location where failure has occurred while gradually increasing a voltage outputted from the PCS for ESS; and cutting-off the location where the failure has occurred and increasing the voltage outputted from the PCS for ESS up to a normal operation level.
