Abstract

This paper presents a cascading failure simulation algorithm with a novel stage division method, while considering dynamic load variation during the cascading propagation process. By accurately estimating the duration of each cascading failure stage, a receding-horizon optimal control model is further presented to mitigate the effects of severe line-overload disturbances and prevent the propagation of outages in electrical power systems. Specifically, the mitigation strategy adaptively adjusts branch flows by re-dispatching generation and load shedding, while taking into account ramping limits and available time duration to determine optimal control actions of each stage. Numerical simulations on the IEEE 118-bus system illustrate effects of the proposed algorithms with load variation and mitigation control strategy.
