MICROGRID SYSTEM, AND METHOD FOR MANAGING MALFUNCTION

WIPO Patent Application WO/2018/105989

A1

A microgrid system, which is provided with a plurality of decentralized power sources, a plurality of decentralized subordinates, and paths connecting the decentralized power sources and subordinates, according to the present invention may comprise: an ESS for storing power supplied from a part or all of the decentralized power sources, and providing the stored power to a part or all of the decentralized subordinates; an ESS PCS for converting the power stored in the ESS to alternating current power appropriate for the microgrid and supplying thereto, and equipped with a cut-off means for cutting off the connection to the microgrid in abnormal situations; and a control apparatus, when a malfunction is sensed in the microgrid, for gradually increasing the voltage outputted from the ESS PCS and managing the malfunction.
