摘要
提出了采用准稳态功率分布因子并结合复杂网络的基本测度来建立电力系统复杂网络特征模型,该模型不仅能够反映元件之间的拓扑连接关系,而且能反映系统实际潮流的分布情况,并据此研究系统元件的重要性。考虑电力系统满足终端负荷需求的效率,以失负荷率来建立元件的脆弱性模型。提出了从元件的重要性来探索元件脆弱性的方法及算法流程。IEEE算例分析结果验证了所述模型及算法流程的可行性。
Based on complex network theory,a complex network model of power systems is proposed using quasi-steady power transfer distribution factor（PTDF）,which can not only reflect the topological connection between components but also the actual power flow distribution.The component important can be analyzed with this model.Considering the efficiency for satisfying terminal load requirement of power systems,load loss rate is used to build the model of component vulnerability.The method of analyzing component vulnerability is presented with a program flowchart.Finally,results of IEEE case studies are used to verify the feasibility of the proposed model and the algorithm.
