中文摘要：

从结构模型的层次简述了复杂网络的相关研究，并根据文献中的研究成果，分析说明了电力网络所具有的符合复杂网络共性的性质，即小世界性和无标度性。概述了复杂网络理论在电力系统中的应用，重点说明了利用复杂网络分析大停电事故的方法和意义，以及如何从复杂网络的角度来分析和研究电力网络的动态特性。总结了目前复杂网络研究尚需解决的问题并预测了复杂网络在今后的电力网络研究中的作用及其发展趋势。

英文摘要：

The research on complex networks is briefly presented. Based on the achievements of many documentations, it is proved that the powe grid has the characteristics of small-world and scale-free, which are the generalities of complex networks. The application of the complex network theory to the power grid is introduced, and the method and importance of using the theory to analyze blackouts are illuminated, as well as how to analyze the dynamic characteristics of power grids based on the theory. Problems that shold be solved for complex networks are summarized, and the role of complex networks in power system study is proposed, as well as its development tendency.
