Abstract :
This paper presents an approach which includes voltage stability considerations in the adequacy assessment of a composite power system. A fast technique for the probabilistic assessment of voltage stability is presented which can be used in conjunction with detailed contingency evaluation in a composite system adequacy assessment. Voltage stability is quantified using an indicator that can be easily included in the framework of an existing composite power system adequacy program. The effect on the adequacy indices (load point and system indices) of incorporating voltage stability constraints is illustrated by application to the IEEE-Reliability Test System
