Abstract :
This paper presents the foundations of controlling unstable equilibrium point (CUEP) theory for stability assessment of two-time-scale power system models. A conceptual two-time-scale CUEP method is developed. The two-time scale CUEP method is faster and more robust as compared to the traditional CUEP method. Furthermore, more insight into power system dynamics and less conservative estimates of the stability region and critical clearing time are obtained.
