Voltage Flicker Parameters Estimation Using Shuffled Frog Leaping Algorithm and Imperialistic Competitive Algorithm

Abstract

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