Towards Incorporating Protection and Uncertainty into Cascading Failure Simulation and Analysis

We advance the state-of-the-art in cascading failure simulation through an integrated modeling of system dynamics and protection coupled with data processing that analyzes the simulation results. An enhanced version of the TS3ph-CAPE simulator is used to produce the cascading data. The cascading data is processed to produce metrics describing the cascading size and risk, and to identify critical components contributing most to the cascading risk

Nonlinear Contingency Screening for Voltage Collapse

A method for estimating the severity of generator unit outage and multi-terminal branch outage contingencies with respect to voltage collapse in large-scale electric power systems which includes the steps of estimating a post-contingency saddle-node bifurcation induced voltage collapse point of an electric power system following a set of generator unit outages and/or a set of branch outages and calculating a distance to collapse of said power system. The post-contingency voltage collapse point is determined by application of a nonlinear contingency screening method.Sponsorship: Illinois Institute of TechnologyUnited States Paten
