基于复杂网络理论的电网分区及断面搜索方法
Subarea Division and Transmission Sections Search Method Based on Complex Network Theory
摘要
Abstract
In order to solve the defect of tradition edge betweenness which takes the shortest path as the only path of power flow,this paper proposes the weighted maximum edge betweenness.This index considers both the influences of network topology and current operation mode on subarea division,which makes the subarea division is more suitable for real power network.Then,this paper proposes the ending criterion of subarea division to effectively utilize the key branches,which reduces the computation amount and prevents the isolated nodes from being a single zone.Finally,this paper obtains the transmission sections by searching the cut sets of network based on the subarea division.A case study of practical system verifies the feasibility of this method in key section search.Compared with the existing section search methods,the proposed method can get more fragile sections and neither depends on the selection of overload branches,nor requires the calculation of all cut sets,which can be better applied to the actual power grid.关键词
