Abstract
The inconsistency of the battery modules will lead to overcharging and over-discharging of the grid connected energy storage system. For the modulation strategy of cascaded H-bridge inverter, this paper proposes a new state of charge (SOC) equalization control strategy, which can quickly realize equalization control in one phase and between phases without over-modulation. The simulation results show that the new control strategy has a significant effect, which greatly improves the speed of SOC balancing compared with the traditional SOC equalization control strategy.
