Transient Stability Assessment Considering Hard Limits on Dynamic States
Omar Romay, Ricardo Martínez-Parrales, Claudio R. Fuerte‐Esquivel
Abstract
This letter proposes a new way for including hard limits associated with control devices in the formulation of the transient stability problem. The inequality constraints representing hard limits are transformed into a set of equality constraints by using the concept of complementarity constraints and the Fisher-Burmeister merit function. This set of constraints are added to the rest of the equations representing the dynamics of an electric power system for a unified framework of analysis, where hard limits are simultaneously and automatically handled during the numerical solution of the transient stability problem.
