基于容量介数指标的电网脆弱线路识别
Vulnerable line identification of power grid based on capacity betweenness index
摘要
Abstract
A new betweenness index and network efficiency index are proposed to identify vulnerable line and to study the spread mechanism of cascading failure. The method not only emphasizes the effect of the topological characteristics on the cascading failures, but also considers the line transmission capacity and efficiency of the network to make up for the shortage of the topology betweenness index which only considers the structural characteristics without considering the electric parameters, thus the new betweenness can identify the most vulnerable parts of the power grid more effectively. IEEE39-bus system is calculated and compared with previous research results. The research shows that the lines which have heavier load and are on the important transmission channel are vulnerable, and if these lines are attacked, it may cause blackouts.关键词
