Abstract
Under modern deregulated environment, both utilities and customers are concerned with the power quality improvement but with different objectives/interests. The utility reconfigure its power network and install mitigation devices, if needed, to improve power quality. The paper presents a strategy for selecting cost-effective solutions to mitigate voltage sags, the most frequent power quality disturbance. In this paper, mitigation device(s) is/are inducted in the optimal network topology at suitable places for their better effectiveness for further improvement in power quality. The optimal placement is looked from utility perspectives for overall benefit. Finally, their performance is evaluated on the basis of reduction in total number of voltage sags, reduction in total number of process trips and reduction in total financial losses due to voltage sags.
