| 摘 要： | 为了有效发掘出网络中的重要环节,提出了一种综合网络结构和节点动力学的电网关键节点识别方法,该方法结合两种已有的节点重要性评价指标——度中心性和接近中心性,同时定义和网络动力学相关的两个指标——临界同步耦合强度和失同步扩散时间。综合考虑4种性能指标的影响来确定节点的重要性,克服了单一评价指标的片面性,可以得到比使用单一评价指标更为准确的节点重要性评价结果。在IEEE14和IEEE57节点系统上进行仿真测试,实验结果验证了方法的合理性和有效性。

| Abstract: | In this paper, in order to effectively discover the important links in a network, a method of identifying critical nodes in a power network is proposed, which is based on the network structure and the node dynamics.This method combines two kinds of existing node importance evaluation indicators, which are the degree centrality and the closeness centrality, at the same time, defines two evaluation indicators considering the network dynamics.The importance of a node is determined by comprehensive considering the influence of four kinds of evaluation indicators, which overcomes the one sidedness of single evaluation indicator, can get the more accurate node importance evaluation result than using single evaluation indicator.Simulation test on IEEE14 and IEEE57 node systems verifies the rationality and effectiveness of the proposed method. |
