Measurement of magnitude and frequency of the components of voltage flicker is very important for monitoring and controlling voltage flicker efficiently to improve the network power quality. This paper introduces a new method for measurement of multiple flicker signals parameters using particle swarm optimization based technique. In this paper, we estimate magnitude of fundamental voltage and multiple flicker magnitudes and frequencies with proposed method. The goal is to minimize the error of the estimated magnitudes and frequencies via a designed fitness function. At first we introduce voltage flicker and its measuring techniques. Then voltage flicker model is analyzed. The proposed method is described and applied to a test case.
