摘要：
Comprehensive argumentation and evaluation of the key issues of the transformerless cascaded H-bridge converter applied in battery energy storage system (BESS) were performed from the aspects of topology, control, and design and experiment verification. A unified balance control scheme was proposed in this paper, which reduced the complexity of the whole control scheme and integrates the control under unbalanced grid voltage, module fault-tolerant control and interphase state of charge (SOC) balancing control together. In order to verify the feasibility of the proposed control scheme, a downscaled experimental prototype was built up in the laboratory. The suppression of common-mode current among modules and the second-order rippled current of the battery were discussed in detail. Then, the optimal design method of the cascaded H-bridge converter for BESS was proposed. We have designed a 10kV/2MW/2MW∙h battery energy storage system based on cascaded H-bridge converter (CHBC-BESS). Supported by the national high technology research and development of China 863 program, the first practical engineering demonstration application was performed at the Baoqing energy storage power station in Shenzhen in 2014. We has accumulated rich experience and operating data in practice, which lays a foundation for the promotion and application of CHBC-BESS. © 2020 Chin. Soc. for Elec. Eng.
