Beschreibung
Zusammenfassung:	The present invention provides a frequency control system which can reduce charging and discharging costs of an energy storage system. According to an embodiment of the present invention, the frequency control system comprises: a power supply unit generating power to supply the power to a system unit; an energy storage system including at least one battery and maintaining a frequency of the system unit through charge and discharge of the battery; and a system operation system controlling the energy storage system. The system operation system calculates a cost function from future estimation electricity costs to determine the amount of charging and discharging of the battery. 본 발명의 일 실시예에 따른 주파수 제어 시스템은 전력을 생산하여, 계통부로 공급하는 전력 공급부, 적어도 하나의 배터리를 포함하고, 상기 배터리의 충전 및 방전을 통하여, 상기 계통부의 주파수를 유지하는 에너지 저장 시스템, 및 상기 에너지 저장 시스템을 제어하는 계통 운영 시스템을 포함하고, 상기 계통 운영 시스템은 미래의 추정 전기비용으로부터 비용함수를 산출하여, 상기 배터리의 충전 및 방전량을 결정할 수 있다.
