Comparison on Two Harmonic Current Determinate Methods of P-Q and Ip-Iq

This paper implements a comparison on p-q and i_p-i_q methods. The simulations demonstrated that it gives same accurate results in case source voltage is symmetric and undistorted. In vice versa case the harmonic current can be detected accurately by i_p-i_q method, while the p-q method gives results are not accurately.
