Abstract

Detection of flicker sources is the first step to mitigate the effect of flicker in power system. In this paper, in order to reduce the number of measurement devices, instantaneous voltages are estimated by using state estimation methods and then root mean square of the voltages and currents variation are detected and then sign of flicker powers is obtained in selected branches. By comparing the sign of flicker power with direction of fundamental active power, the places of flicker sources are obtained. For validation, the 6-bus non-radial network is simulated and algorithm for flicker sources detection is tested in this paper. The simulations results show that by using the proposed algorithm, all flicker sources in a non-radial network can be detected correctly.
