Obtaining statistics of cascading line outages spreading in an electric transmission network from standard utility data

Abstract

We show how to use standard transmission line outage historical data to obtain the network topology in such a way that cascades of line outages can be easily located on the network. Then we obtain statistics quantifying how cascading outages typically spread on the network. Processing real outage data is fundamental for understanding cascading and for evaluating the validity of the many different models and simulations that have been proposed for cascading in power networks.

Revised and expanded version with minor corrections and a new section illustrating use of data to validate a simulation. Will appear in IEEE Transactions on Power Systems
