The Vulnerability Analysis On Power Communication Networks Based On Complex Network Theory

The research on vulnerability of electric power communication network is of great importance to ensure the safe operation of the system and strengthen the power grid. This paper takes the complex network theory as the foundation; make the vulnerability analysis on the electric power communication network. First, the operation of network is analyzed and the nodes, links and integrated vulnerability analysis models are given; and then the actual electric power communication network is taken as an example, topology modeling, static geometric parameters computing and characteristic analysis are completed, then according to the value of degree and betweenness, the network vulnerable points are identified; Aimed at different failure modes, vulnerable attack to the network is carried on. According to the simulation result, the impact of structural vulnerability to the network is analyzed; finally, sort the vulnerability of electric power communication network of nodes and links, the most vulnerable points of the network are pointed out, and the impact of physical and structural vulnerability on the integrated vulnerability is analyzed.
