Abstract

Complex network theory is applied to study the inherent vulnerability of power transmission grid under cascading failures. It introduces the complex analysis model and some basic conceptions of network characteristic parameters and its algorithm to calculating network efficiency, then it applies proposed algorithm to analyze the complex characteristics of power grid while occurring the cascading failures triggered by link failures, and qualitatively analyzes the resistible ability of power grid in case change of topological structure. Taking advantage of qualitative simulating results, we may determine the vulnerable regions which affect the performance of power transmission network.
