The Model of Interdependent Networks on China Power Grid

Abstract

On the basis of topology analysis, the novel interdependent networks model on China Power Grid is proposed in this paper. Different from prior modeling on China Power Grid which is limited in partial region, we model the multi-regional interdependent networks. Through addition considering heterogeneity of nodes in interdependent networks, it is found that regional interdependent networks can still operate in islanding state, which can prevent propagation of failure in networks. The figures in coupled networks verify robustness of BA-WS networks facing attack, and the results obtained from simulation reveal high robustness of multi-regional interdependent networks and further prove the rationality of layout of China Power Grid.
