Cascading failures in large-scale electric power transmission systems are an important cause of blackouts. Analysis of North American blackout data has revealed power law (algebraic) tails in theâ€¦ (More)

Large blackouts typically involve the cascading outage of transmission lines. We estimate from observed utility data how much transmission line outages propagate, and obtain parameters of aâ€¦ (More)

In order to study the complex global dynamics of a series of blackouts in power transmission systems a dynamical model of such a system has been developed. This model includes a simple representationâ€¦ (More)

We define the voltage across an area of a resistive network by suitably combining voltages at buses (nodes) on the border of the area. The new voltage across the area satisfies circuit laws. The sameâ€¦ (More)
