چکیده

Measurement of magnitude and frequency of the voltage flicker is very important for monitoring and
controlling voltage flicker efficiently to improve the network power quality. This paper presents two
new methods for measurement of flicker signal parameters using Shuffled Frog Leaping Algorithm
(SFLA) and Imperialist Competitive Algorithm (ICA). This paper estimates fundamental voltage and
flicker magnitudes and frequencies with proposed methods. 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. At the next part, a review
of SFLA and ICA is presented. These methods will be applied to a test voltage signal and the results
are be analyzed.
