Abstract
To effectively identify the critical links in power grid and prevent cascading failures,load betweenness and electric Euclidean distance are proposed to identify the critical nodes and lines in power grid. Firstly ,load betweenness is proposed by considering the distinction between nodes and lines. Then synthesizing the line betweenness and maxi⁃mum transmission capability of lines,electric Euclidean distance is proposed. Considering the influence of global im⁃portance of nodes,and weighted betweenness,average degree and maximum transmission capability of lines on the power flow distribution,power grid is simplified as directed and weighted network with the constraints of node degree difference and power transmission,which is in accordance with the applications of power system. Simulation results on IEEE 39-bus system and comparison with other identification methods indicate the effectiveness of the model.关键词
