The approach of mining critical nodes for power networks based on higher-order structure
Mining key nodes in power networks is of great significance to improve the robustness,stability and reliability of the power system.On the basis of the high-order structure that frequently exists in the pow-er network,this paper uses the high-order network analysis method and introduces the fuzzy comprehensive decision-making technology,and proposes a key node mining method which integrates the low-order and high-order structure information of nodes.The experiment and verification are carried out on three real pow-er network data sets,and the proposed method is evaluated from two aspects of network structure and func-tion.The results show that compared with the classical low-order methods,the proposed method can identi-fy the key nodes in power network more accurately,and demonstrate the necessity of considering the high-order information of nodes,and provide a new method for the mining of key nodes in power network.
