Power grids Vulnerability Analysis Based on Combination of Degree and Betweenness
This paper proposes an analysis method of power grids vulnerability based on complex networks.The method effectively combines the degree and betweenness of nodes or lines into a new index.Through combination of the two indexes,the new index can help to analyze the vulnerability of power grids.Attacking the line of the new index can obtain a smaller size of the largest cluster and global efficiency than that of the pure degree index or betweenness index.Finally,the fault simulation results of IEEE 118 bus system show that the new index can reveal the vulnerability of power grids more effectively.
