Abstract
Voltage instability in power system is becoming more and more important because of the regular growth of power system and lack of efficiency in reactive power management. The voltage instability of a power system is associated with a voltage drop. Voltage drop has a cumulative effect unless efficient reactive power sources are available for voltage regulation. In this paper, the voltage stability region of IEEE standard bus systems is visualized using P-Q curve technique. Voltage stability margins are also visualized using local measurement techniques. Then, the change in stability margin is observed by introducing FACTS and DG. Optimum location of installation of these devices is determined.
