考虑短路比约束的边远区域微电网无功调节资源优化配置方法OA

To address the widespread issue of significant voltage deviations in microgrids in remote areas,a collabora-tive configuration optimization method for multi-source heterogeneous reactive power regulation resources is proposed in this paper by taking into account short-circuit ratio constraints.First,aimed at the differences in regulation mechanisms and constraints of reactive power regulation resources such as PV inverters,energy storage converters and reactive pow-er compensation equipment,a unified equipment model incorporating short-circuit ratio constraints and reactive power dynamic characteristics is constructed.Second,based on the multi-time-period operation characteristics on a typical op-erating day,a configuration optimization model for reactive power regulation resources is established with multiple ob-jectives including investment cost,network losses and voltage deviation,which is further solved using a multi-objective particle swarm optimization algorithm.The analysis of a case study demonstrates that the proposed method can achieve rational spatial and temporal allocation of reactive power capacity while satisfying short-circuit ratio constraints.It signif-icantly improves voltage levels at weak network end nodes,reduces line current and network losses,and effectively mit-igates inverter derating issues,exhibiting strong engineering applicability and promotion value.
