摘要：

Cascaded power conversion system was used in battery energy storage system. It can be connected to mediumvoltage grid directly and expanded to larger capacity easily. Without 50Hz booster transformer, medium voltage cascaded power conversion system can reduce power loss. In 2011, the China Southern Power Grid launched the project of 2MW/10kV battery energy storage system. In this paper, the design requirement of the cascaded power conversion system, main circuit topology and power unit topology were described. Then parameters of key part were designed, and power loss was analyzed. Besides, a prototype was built to verify the feasibility of the design
