A Model for Structural Vulnerability Analysis of Shipboard Power System Based on Complex Network Theory

A structural vulnerability analysis method of shipboard power system based on complex network is proposed in this paper. In this paper, the shipboard power system is modeled as a complex network, and topological characteristics of shipboard power grid are analyzed. Two structural vulnerability criterions, which are electric betweeness of node and cabin respectively, are defined to evaluate the importance of network elements and element groups in a cabin, and analysis structural vulnerability. The results of attack tests on a typical shipboard power system show that the structural vulnerability of shipboard power system has close relationship with topological structure and the cabin betweenness can effectively identify the structural vulnerability of shipboard power system.
