Research on node importance of power communication network based on Multi-Attribute Analysis

As the support network of power grid, the reliability and stability of power communication network structure become more and more important with the continuous expansion of power grid scale. Identifying and protecting important nodes in the power communication network in advance is an effective method to improve the robustness of the network. Therefore, this paper proposes a comprehensive evaluation method for the importance of nodes in the power communication network based on MADM (Multiple Attribute Decision Making). This method considers three indexes: degree centrality, betweenness centrality and PageRank value. By determining the weight of each index objectively and calculating the closeness of each node scheme to the ideal scheme, the comprehensive evaluation result of the importance of the node is obtained. When determining the weight of each index, the contrast and correlation of the indexes are considered at the same time, so that the result is closer to reality. The experimental results show that the proposed algorithm is more reliable and effective than the traditional method in ranking the importance of nodes in power communication network
