Cascading Failure Model of Interdependent Power Networks Based on Load Redistribution

Abstract

With the development of networks, the relationships between networks have also been increasingly intimate. It is envisioned that these interdependent networks are more vulnerable. In order to study the robustness of interdependent networks, in this paper, we characterize a load redistribution model based on distance and cascading failure model about interdependent communication network and power network. The failure model joined the load factor on the basis of the penetration model. We analyze the influence of different distribution distance threshold to interdependent networks. The simulation shows that global redistribution yields better performance and enough capacity cannot prevent cascading failure completely.

A Review of CPS Design and Vulnerability Analysis

“…In [9], Wu, Zhang, Wu and Yang studied the cascading failure of interdependent networks and presented a network topology-based cascading failure model. Key nodes in sophisticated power grids may be identified by using an electric range and node electric coupling connection measure provided by the author in [10].…”
