Abstract :
The preventive/corrective control for voltage stability is an indispensable part of on-line voltage monitoring system. Hidden trouble of voltage stability could be eliminated by cooperation of preventive control and corrective control, thus the operating point could be in secure area continually. In this paper, a 168-bus real power system was investigated to illustrate how to solve optimal control problem using primal-dual interior point method (PDIPM). Additionally, this paper presents a new scheme of voltage collapse preventive control problem, coordinating the optimal power flow (OPF) computation with the automatic voltage control (AVC) system. This new scheme proposed has been recognized by engineering practice.
