Branching Process Models for the Exponentially Increasing Portions of Cascading Failure Blackouts
We introduce branching process models in discrete and continuous time for the exponentially increasing phase of cascading blackouts. Cumulative line trips from real blackout data ...

An Estimator of Propagation of Cascading Failure
— We suggest a statistical estimator to measure the extent to which failures propagate in cascading failures such as large blackouts. The estimator is tested on a saturating bran...

A probabilistic loading-dependent model of cascading failure and possible implications for blackouts
Catastrophic disruptions of large, interconnected infrastructure systems are often due to cascading failure. For example, large blackouts of electric power systems are typically c...

Propagation of Load Shed in Cascading Line Outages Simulated by OPA
We estimate with a branching process model the propagation of load shed and the probability distribution of load shed in simulated blackouts of an electric power system. The avera...
