Model for cascading failures in complex networks.
Large but rare cascades triggered by small initial shocks are present in most of the infrastructure networks. Here we present a simple model for cascading failures based on the dynamical redistribution of the flow on the network. We show that the breakdown of a single node is sufficient to collapse the efficiency of the entire system if the node is among the ones with largest load. This is part...
متن کاملAnalysis of Cascading Failures in Power Networks
This thesis studies the characteristics of cascading failures in a simulated linear swingequation model for simple power networks. The model transitions from displaying only small average failure size to undergoing large average failure size as the loading of the system is increased. For some parameter values, the transition region becomes critical, and it exhibits failures of all sizes whose d...
متن کاملCascading Failures in Spatially-Embedded Random Networks
Cascading failures constitute an important vulnerability of interconnected systems. Here we focus on the study of such failures on networks in which the connectivity of nodes is constrained by geographical distance. Specifically, we use random geometric graphs as representative examples of such spatial networks, and study the properties of cascading failures on them in the presence of distribut...
متن کاملCascading Failures in Finite-Size Random Geometric Networks
The problem of cascading failures in cyber-physical systems is drawing much attention in lieu of different network models for a diverse range of applications. While many analytic results have been reported for the case of large networks, very few of them are readily applicable to finite-size networks. This paper studies cascading failures in finite-size geometric networks where the number of no...
متن کاملOn the Dynamics of Cascading Failures in Interdependent Networks
Cascading failures in interdependent networks have been investigated using percolation theory in recent years. Here, we study the dynamics of the cascading failures, the average and fluctuations of the number of cascading as a function of system size N near criticality. The system we analyzed is a pair of fully interdependent Erdös-Rényi (ER) networks. We show that when p is close to pc, the wh...
