The used of Fast-Fourier Transform (FFT) demodulation for flicker source identification

Flicker Power Algorithm has been found to be acceptable techniques for flicker source identification in power system. It is due to the scheme of this algorithm that follows the acceptable IEEE Flicker Meter standard. However, these Flicker Power Algorithm techniques are facing the deficiency due the inaccurate flicker power calculation. In this paper, the Flicker Power Algorithm based on Fast Fourier Transform (FFT) demodulation method is proposed to overcome such deficiency. The IEEE 13 bus test system with different location of flicker source has been used to evaluate the effectiveness of the proposed technique.
