解决模块化中压直流变换器光伏功率失配问题的环形功率平衡拓扑与潮流优化策略

Power balancing topology is an effective solution to the photovoltaic power mismatch problem in a medium voltage dc system. However, the existing power balancing topologies are all based on a chain structure, in which the mismatched power needs to be transferred through multiple power balancing units (PBUs). In the case of severe power mismatch, the accumulated balancing power is very large, resul...
