Abstract
To identify the direction of cascading failure efficiently when the power grid blackouts happen, the current betweenness index was proposed in this paper based on Kirchhoff's laws to find out the vulnerable lines. The index was established under the model in which power flow transmitted alongall the possible paths, and meanwhile the maximum current and the topological characteristics of the network were also taken into account. The current betweenness index could reflect the characteristics of the actual power grid better than the electric betweenness. The differences in the maximal transmitting capability of the IEEE39-bus system under two kinds of attack showed the correctness and rationality of the current betweenness index.关键词
