Abstract :

Measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. This paper presents twonew methods for measurement of flicker signal parameters using Shuffled Frog Leaping Algorithm(SFLA) and Imperialist Competitive Algorithm (ICA). This paper estimates fundamental voltage andflicker magnitudes and frequencies with proposed methods. The goal is to minimize the error of theestimated magnitudes and frequencies via a designed fitness function. At first, we introduce voltageflicker and its measuring techniques. Then voltage flicker model is analyzed. At the next part, a reviewof SFLA and ICA is presented. These methods will be applied to a test voltage signal and the resultsare be analyzed.
