Abstract
Voltage sag is the major power quality problem, which could disrupt the operation of sensitive equipment. This paper presents the applications of instantaneous energy direction for voltage sag source detection. Simulations have been performed to provide the analysis for system with distributed generation units. The studies show that the presented method can effectively detect the location of the voltage sag source.
