为保证分布式能源出力和负荷波动时微电网中能量平衡及稳定，分布式储能单元(distributed energy storage units， DESUs)工作于充放电模式，然而，受线路阻抗不一致的影响，DESUs充放电过程中会出现荷电状态(state-of-charge， SoC)不平衡现象，造成过充电或过放电，减短了储能单元的使用寿命。该文基于下垂控制提出 SoC 平衡控制方法，实现 SoC 平衡；同时提出基于低带宽通信的电压恢复控制策略以补偿由下垂控制引起的电压偏差，SoC平衡和电压恢复由本地脉冲协调控制，两者互不干扰。讨论分析了不同工况下该策略的特性，证明了SoC平衡和电压恢复的有效性。“,”In order to balance power requirements and improve system stability when the distributed energy resources or power demand of loads change, it is necessary for the distributed energy storage units (DESUs) to charge or discharge. However, the state-of-charge (SoC) for DESUs diverges during charging and discharging process due to the unbalanced line impedances, subsequently resulting in overcharging or overdischaring, which significantly shorten the life of DESUs. This paper presents a SoC balancing method based on droop control and a voltage restoration method based on low bandwidth communication to compensate the voltage deviation caused by droop control. The SoC balancing and voltage restoration are regulated coordinately by local pulse. This paper investigates and analyzes the performance of this control strategy and further demonstrates the effectiveness of SoC balancing and voltage restoration.
