Abstract :
This paper compares various generation direction methods in static voltage stability study in power systems. A new approach, namely economic generation direction (EGD) approach, is proposed to find the generation direction that minimizes the total operating cost. The proposed method is compared with conventional and the most recent generation direction methods, namely maximum loading margin and optimal generation direction methods, in terms of voltage stability margin and total operating cost. PV curve, loading margin and total operating cost are compared in the modified IEEE 14-bus test system. The study provides an idea for independent system operator about what kind of generation directions could be adopted in different power system scenario
