| 摘 要： | 电网分区是运行和保护电网的重要课题。以关联强度代替传统的邻接矩阵,定义电气关联强度(ECS)用来反映电网中任意节点之间的电气特性,并基于发电机节点和负荷节点之间的供电关系提出供电关联强度(PSS)。在经典的模块度(Modularity)基础上,结合供电关联强度提出供电模块度(PS-Modularity)的概念,并基于此对Newman快速算法进行改进,以自动识别供电社团结构。

| Abstract: | Partitioning of power grids is important for operation and protection.Coupling strength is proposed to replace conventional adjacency matrix.Electrical coupling strength(ECS)was defined to reflect electrical characteristics between any buses in power grids.Then power supply strength(PSS)was proposed based on ECS only from generation nodes to load nodes.Based on the classical modularity,the concept of power supply modularity(PS-Modularity)was proposed in combination with the power supply strength.Newman fast algorithm was revised on the basis of PS-Modularity to automatically detecte power supply communities. |
