The present invention relates to an energy storage system. The energy storage system comprises: an energy storage device configured to store energy generated from a renewable energy plant; a power management device configured to monitor the total amount of power generated from at least one renewable energy plant in a plurality of areas, determine an operation mode of the energy storage device based on a result of monitoring a reference capacity of an integrated line, through which power is transmitted to the plurality of areas, and the total amount of power, and control a capacity of power flowing through the integrated line according to the operation mode; and a power conversion device configured to receive a command corresponding to the operation mode from the power management device and control an operation of the energy storage device according to the command. According to the present invention, it is possible to contribute to the stabilization of the power system through the energy storage system without increasing the number of new renewable energy plant. 에너지 저장 시스템은, 신재생 에너지 발전소에서 생성된 에너지를 저장하는 에너지 저장 장치; 복수의 지역 내의 적어도 하나의 신재생 에너지 발전소에서 생산된 전체 전력량을 모니터링하고, 상기 복수의 지역의 전력을 송전하는 통합 선로의 기준 용량 및 상기 전체 전력량을 모니터링 한 결과에 기초하여, 상기 에너지 저장 장치의 동작 모드를 결정하고, 상기 동작 모드에 따라 상기 통합 선로에 흐르는 전력 용량을 제어하는 전력 관리 장치; 및 상기 전력 관리 장치로부터 상기 동작 모드에 대응하는 명령을 수신하고, 상기 명령에 따라 상기 에너지 저장 장치의 동작을 제어하는 전력 변환 장치를 포함할 수 있다.
