The present invention relates to a system for storing generated power, comprising: an energy storage system (ESS) which stores power; a branch line which transmits generated power of a generator connected to a transmission substation to the ESS; a grid-connected transformer which converts high-voltage generated power formed on the branch line into low-voltage generated power; a power conversion device which converts the low-voltage generated power into direct current power; and a power management device which acquires failure information on a transmission path including the transmission substation, controls, when failure on the transmission path is detected through the failure information, the power conversion device to process the whole or a part of the generated power as charging power of the energy storage system (ESS). 본 발명은, 전력을 저장할 수 있는 에너지저장장치(ESS); 송전단변전소와 연결되는 발전기의 발전전력을 상기 에너지저장장치(ESS)로 전달할 수 있는 분기선로; 상기 분기선로에 형성되는 고전압 발전전력을 저전압 발전전력으로 변환하는 계통연계변압기; 상기 저전압 발전전력을 직류전력으로 변환하는 전력변환장치; 및 상기 송전단변전소를 포함하는 송전경로에서의 고장정보를 획득하고, 상기 고장정보를 통해 상기 송전경로에서의 고장이 감지되면 상기 전력변환장치를 제어하여 상기 발전전력의 전부 혹은 일부가 상기 에너지저장장치(ESS)의 충전전력으로 처리되도록 하는 전력관리장치를 포함하는 발전전력저장시스템을 제공한다.
