The robustness of different scale power grids is analyzed based on complex network theory in terms of electrical … betweenness and weighted efficiency. The robustness of a power grid does not always increase monotonically with the capacity. This … property is different from the results obtained in previous studies, which have indicated that the robustness increases …

In recent years the rapid development of complex network theory has provided a new angle on the vulnerability analysis of a power grid. However, current analysis models are usually general ones that may ignore some specific features of power systems. In order to address the issue, this paper...
