Abstract :
This paper proposes a method of power system voltage stability enhancement by rescheduling the real power outputs of the generators. A regression-based method is proposed for computing sensitivities of the voltage stability margin with respect to generator outputs. Optimum generator outputs are found by using the sensitivity information, to enhance the voltage stability margin for multiple contingencies. Case studies are presented to illustrate the effectiveness of the proposed method
