Abstract :
In this paper, effect of realistic load direction based on a practical load variation is investigated in static voltage stability study. A practical load variation is represented by actual daily load curves of a practical power system, namely, Thailand power system, which are used to identify the realistic load direction. The use of the realistic load direction provides a more practical solution in terms of loading margin or voltage stability margin in static voltage stability study. The practical load direction is validated and compared with conventional load direction in the IEEE 14-bus test system under various system conditions
