A model for static vulnerability analysis of shipboard power system based on complex networks theory

A modeling method for shipboard power network static vulnerability analysis is proposed from a network theoretic prospect, to study the survivability of shipboard power system. In this model, two statistical indicators, which are electric betweeness of node and that of cabin, are defined to indicate the importance of network elements and element groups, and the bus transfers are modeled as node couples. The static vulnerability of shipboard power network with four power stations is analyzed, and the result shows the network is robust under random attacks and vulnerable under intentional attacks.
