Abstract :
This paper investigates the effect of induction motor stalling on power system voltage stability assessment. A new time-scale decomposition is suggested when a single motor stalls. This allows a better security margin assessment in cases where motor stalling has no serious consequences on system operation. Case studies on a two motor system and a 34-bus system demonstrate the applicability of the proposed approach
