基于复杂网络社团相似度的电网分区研究

Study of Power Grid Partition Based on the Similarity of Complex Network Communities

基于复杂网络相似度,提出了一种电网分区方法。首先,给出了加权电网的节点相似度矩阵和社团相似度的计算方法,利用节点相似度将各节点预分裂。然后,利用社团相似度进行凝聚分区。最后,利用模块度指标获得最优分区个数。仿真结果表明,所提方法适用范围广且能够快速有效地将电网分成不同分区,分区内节点的相似度较高,且分区后的电网具备较好的社团结构特性。

Based on the similarity of complex networks,a grid partition method is proposed.First,the calculation method of the node similarity matrix and community similarity of the weighted grid is proposed.The node similarity is used to pre-split each node,and then the community similarity is used to condense the partitions.The modularity index is used to obtain the optimal number of partitions.The simulation results show that the method in this paper can quickly and effectively divide the power grid into different partitions.The nodes in the partition share close similarity,and the grid after the partition is superior in community structure characteristics.
