Research on Vulnerability Analysis of Power Communication Network Based on Complex Network Theory
Based on the central role of power communication network in modern power system,this paper deeply analyzes its network topology and vulnerability under different attack and failure modes.Firstly,the paper analyzes the small-world and scale-free characteristics of power communication network by constructing a mathematical model,and then discusses the degree distribution,node vulnerability and failure modes of the network.On this basis,this paper puts forward targeted protection strategies,such as protection for high-degree nodes,edge-adding strategy for low-degree nodes and network reconfiguration strategy,aiming at enhancing the network's anti-attack ability and improving its stability.The effectiveness of these strategies is evaluated quantitatively,and the results show that the proposed measures can significantly improve the robustness and efficiency of power communication network.This study not only provides a theoretical basis for vulnerability analysis of power communication network,but also provides practical guidance for network optimization and protection,which is of great significance for ensuring the stable operation of power system.
