Structural Vulnerability Evaluation Model Based on Improved Electrical Betweenness

Abstract:

Several blackouts happened in a worldwide area, it exposures the vulnerability of continual increment of power system scale. The weak link has a strengthening effect on the spread of the accelerated failure, and leads to the occurrence of cascading failures, it's a serious threat to the security and stability of the grid. Based on the existing researches, the article proposes a new structure vulnerability evaluation model based on improved electrical betweenness, and verifies the rationality and effectiveness of this model by the analysis of the IEEE-39 node system.
