Using Transmission Line Outage Data to Estimate Cascading Failure Propagation in an Electric Power System

摘要

We study cascading transmission line outages recorded over nine years in an electric power system with approximately 200 lines. The average amount of propagation of the line outages is estimated from the data. The distribution of the total number of line outages is predicted from the propagation and the initial outages using a Galton–Watson branching process model of cascading failure.
