摘要：
One of the recent concerns that power utilities are facing is to maintain the required system voltage stability margin. This paper investigates the effect of generation rescheduling in enhancing the overall system voltage stability margin. A new formulation of generation rescheduling in view of minimization of the slack reactive power injection has been suggested. In addition, conventional optimal power flow (OFF) formulations, with their objectives being the minimization of total generation cost and minimization of total system transmission loss, and another formulation of generation rescheduling in view of the maximization of the minimum singular value of the power flow Jacobian have been studied. All the four formulations have a more realistic voltage dependent model of the generators and the synchronous condensers. The study has been carried out on three sample systems.
