Structural vulnerability of the North American power grid
TLDR
The power grid is robust to most perturbations, yet disturbances affecting key transmission substations greatly reduce its ability to function, and it is emphasized that the global properties of the underlying network must be understood as they greatly affect local behavior.Abstract:
The magnitude of the August 2003 blackout affecting the United States has put the challenges of energy transmission and distribution into limelight. Despite all the interest and concerted effort, the complexity and interconnectivity of the electric infrastructure precluded us for a long time from understanding why certain events happened. In this paper we study the power grid from a network perspective and determine its ability to transfer power between generators and consumers when certain nodes are disrupted. We find that the power grid is robust to most perturbations, yet disturbances affecting key transmision substations greatly reduce its ability to function. We emphasize that the global properties of the underlying network must be understood as they greatly affect local behavior.read more

Catastrophic cascade of failures in interdependent networks
Sergey V. Buldyrev,Sergey V. Buldyrev,Roni Parshani,Gerald Paul,H. Eugene Stanley,Shlomo Havlin +5 more
TL;DR: In this paper, the authors develop a framework for understanding the robustness of interacting networks subject to cascading failures and present exact analytical solutions for the critical fraction of nodes that, on removal, will lead to a failure cascade and to a complete fragmentation of two interdependent networks.
