Power network modeling method based on complex network

Abstract

In order to solve the problem that it is difficult for traditional methods to effectively analyze the generation and propagation process of large-scale cascading failures in power grid macroscopically, a power network modeling method based on complex network is proposed, which strips the power network into physical layer and functional layer twolayer networks. aiming at the two-layer network, the construction method and process of power network model based on complex network theory are proposed, and the calculation models of network characteristic analysis index of two-layer network are proposed respectively. At the same time, an example analysis is carried out based on the actual data, and the complex network models of physical layer and functional layer are built respectively, which provides guidance for the follow-up analysis of the power grid.
