基于复杂网络重叠社区电网节点重要度研究

摘要

With increase of electric power grid structure and development of characteristic of complicated network,tradition-al partition method could not satisfy analysis requirement of large power network while recognition research on key nodes of power system are useful to conduct monitoring and control on safety and stability of the system. Therefore,combining struc-ture of overlapping community of the power grid and system running characteristic as well as considering reactance value,a kind of evaluation index model for power grid node importance was proposed and IEEE 1 1 8 node system was used for calcu-lating verification. The result indicates that this model is of certain practical value.%随着电力网架的不断增大和复杂网络特性的发展，传统的分区方法难以满足大网络分析，而电力系统关键节点的识别研究，有助于对系统的安全稳定进行监测和控制。基于此，结合电网的重叠社区结构和系统运行特性，考虑线路的电抗值，提出了一种新的电网节点重要度评估指标模型，并利用 IEEE 118节点系统进行计算验证，结果表明该模型具有一定的实用价值。
