摘要

本文对集成蓄电池储能的模块化多电平变换器进行了分析，重点讨论了蓄电池向电网注入的电能和蓄电池向电网注入的电能对电容器电压平衡的影响。变频器的控制目标是保持两臂之间的平衡。通过重新定义循环电流以补偿无功功率并重新平衡交流电网电压不对称，仿真结果表明，电池注入的电流不会给变流器带来任何不平衡。

Modular multilevel converters with integrated batteries energy storage

This paper presents the analysis of the modular multilevel converter with integrated batteries energy storage and highlights the influence of the power injected to the grid from the batteries or vice versa on the capacitors' voltage balancing. The control objective of the converter is to maintain a balance between the arms. By redefining the circulating current in order to compensate for reactive power and rebalance the ac grid voltage asymmetries, it is shown through simulation results that the current injected by the batteries does not introduce any unbalance to the converter.
