集成光储中压并网的智能软开关拓扑及其控制策略

This paper proposes a photovoltaic-battery hybrid cascaded smart soft open point (PVBH-SOP) for flexible interconnection in medium-voltage distribution networks, enabling efficient PV-storage aggregation and unbalanced power flow regulation. Its topology, averaged model, three operating modes, and control strategies are presented, validated via MATLAB/Simulink simulation of a 10 kV/2 MW system.

针对中压配电网新能源并网节点柔性互联,提出一种集成光储中压并网的智能软开关(SOP),兼具高效汇集光储资源和改善配电网潮流不均衡分布能力.首先,介绍了光储混合级联SOP(PVBH-SOP)拓扑结构,给出了单级式隔离级联子模块拓扑及其调制策略.其次,建立了PVBH-SOP平均电路模型,分析了其潮流调控原理.然后,给出了PVBH-SOP的3种运行模式,设计了相应控制策略.最后,在MATLAB/Simulink仿真平台上搭建了一套10 kV/2 MW的PVBH-SOP系统,验证了所提PVBH-SOP拓扑与控制策略的有效性.
