Hybrid dynamical system as model for cascading outage in a power system

This paper uses hybrid dynamical systems as a mathematical model for cascading outages in a power system. Hybrid dynamical systems can combine families of flows describing swing dynamics of generators with switching rules describing protection control mechanisms. We refer to data observed in a cascading outage in the September 2003 blackout in Italy and show a hybrid dynamical system by which propagation of outages reproduced is consistent with the data.
