Method for Identifying Critical Nodes in Power Network Based on Integrated Topological and Operational Characteristics
摘要
Abstract
A method for identifying the critical nodes in a power network is proposed in this paper based on the Tsallis entropy and power flow betweenness,which aims to fully identify the critical nodes in the power network by comprehen-sively taking into account its topological and operational characteristics.First,based on the node's structural hole con-straint coefficients and K-shell values,the complexity of the network topology is measured by combing the Tsallis entro-py,and the nonlinear relationship between the local and global criticalities is comprehensively considered to formulate the node's Tsallis entropy index.Second,a power flow tracing algorithm is used to calculate the power flow between-ness of branches between nodes in the power network,and the directionality of power flow is incorporated to establish a power flow betweenness degree index for the node.Finally,the analytic hierarchy process and entropy weight method are used to assign weights for the combination of the node's Tsallis entropy index and power flow betweenness degree in-dex,thereby obtaining a comprehensive evaluation index for node criticality that both satisfies the subjective preference and accounts for the objective data.On this basis,an accurate and comprehensive identification of node criticality for the power network is realized.The feasibility,reasonableness and applicability of the proposed method are verified us-ing IEEE 39-node and 118-node test systems.关键词
