Post-contingency equilibrium analysis techniques for power systems

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Different methods of calculating the post-contingency equilibrium state of a power system are presented and tested. One method utilizes a full Newton's method, and two utilize a standard commercial power flow program. These three methods are illustrated on two small test systems. The results from these simulations are then compared to a dynamic simulation using numerical integration to an equilibrium state, and conventional contingency analysis using only a standard power flow solution.
