Power Control and Equalization Strategy for MMC-BESS
This paper investigates the control strategies for modular multilevel converter-based battery energy storage systems (MMC-BESS). Based on the analysis of topological structure and operational principles of the MMC-BESS, the mathematical model for the AC side is established. A dual-loop control strategy based on feedforward decoupling is adopted to regulate grid-connected power. To improve the battery utilization in the energy storage system, a voltage equalizing control strategy is proposed. Proposed control strategies are verified by simulation models.
