LARGE CAPACITY BATTERY SYSTEM FOR POWER SYSTEM FREQUENCY REGULATION AND LARGE CAPACITY BATTERY OPERATION METHOD

摘要

The present invention relates to a large capacity battery system for managing a large capacity battery used for power system frequency regulation and a large capacity battery operation method. A method for operating a large capacity battery used for power system frequency regulation in a large capacity battery system for managing the large capacity battery according to the present invention comprises the steps of: calculating an estimated frequency regulation signal for the next day using history information of past frequency regulation signals; calculating a bidding capacity and a basic value for the large capacity battery matched to the estimated frequency regulation signal; determining an operation plan using the calculated bidding capacity and basic value; bidding the bidding capacity and basic value for the large capacity battery according to the operation plan on the day ahead frequency regulation market; and when the bidding of the bidding capacity and basic value for the large capacity battery has been successful on the day ahead frequency regulation market receiving a frequency regulation signal from the real time frequency regulation market and storing the same and operating the large capacity battery according to the received frequency regulation signal.
