The medium voltage direct hanging energy storage system has been widely used in high capacity applications, which gets rid of power frequency transformer and is of high conversion efficiency. This paper introduces the medium voltage direct hanging energy storage system topology scheme. In order to improve the battery life and capacity utilization, the in-phase and inter-phase battery equalization control strategies are studied. Finally, the simulation results on medium voltage direct hanging energy storage system prove the correctness and effectiveness of the equalization control strategy.
