20 KW 전력저장전지시스템 개발

The development of 20 KW battery energy storage system

The battery energy storage system has been studied and adopted actively by foreign advanced utilities to use off-peak energy. Korea electro-technology research institute & KEPCO developed a small scale battery energy storage system. This system is composed of a voltage type self commutating inverter and 180 cells of 500 AH lead acid battery. Using the result of operation of the system, we make a conceptual design of MW class system.
