Electric power networks have been Studied as a typical example of real-world complex networks. Traditional models for structural vulnerability analysis appear to be all based on physical topological structure. In this paper, we depict a typical power network as a weighted graph based oil electrical topology by introducing its bus admittance matrix, which embodies the important characteristics of power networks in a much more realistic structure. Furthermore, the numerical Simulation for both the traditional dynamical model and the proposed electrical topological model are investigated based oil the IEEE 300 bus system respectively. The comparison demonstrates that the improved model is more precise and highly efficient for the analysis of structural Vulnerability of power networks. (C) 2009 Elsevier B.V. All rights reserved.
