摘　　要：综述了目前复杂网络理论应用于电力系统的研究现状。首先,论述了利用复杂网络理论对电力系统建模的可行性;其次,从三个方面论证了复杂网络理论中纯粹的拓扑模型难以准确描述电网的实际特性,并对现有文献中的几种典型模型进行了介绍,分析比较了各自的侧重点;然后,详细介绍了复杂网络理论应用于电力线路脆弱性辨识中的两种不同思路:基于拓扑参数法和基于拓扑图分区法。最后,指出将电气元件的特性融入复杂网络系统模型以及建立实时在线的线路脆弱性辨识模型是今后该领域的主要研究方向。A review of the literatures about the application of complex network theory in the power grid is presented. Firstly the feasibility of modeling the power grid based on complex network theory is discussed. The reason why the pure topological model in complex network theory cannot describe the power grid characteristics is pointed out. Some existing improved models are introduced and compared. Moreover, the methods to identify the vulnerable lines based on two different thinking, namely the topological parameter and topology graph partition, are summarized in detail. Finally, it is proposed that the main further researches are blending the characteristics of electrical components into the power grid model and setting up a real-time online vulnerability identification model based on the complex network theory.
