Flicker is one of significant power quality disturbances, which may lead to serious voltage fluctuation. Therefore, the accurate estimation of flicker components plays
an important role in the power quality monitoring and protection of power system. In this paper, a high-resolution technique is proposed to extract the flicker components effectively. Different from the conventional spectral analysis methods, the performance of proposed mechanism would not be influenced by the fundamental frequency deviation, the sampling frequency, and the length of sampled data. With the experimental test, the estimation accuracy and robustness are verified.
