Abstract: Increase in application of non-linear loads will cause power quality issues. In utilizing Distribution generation unit interfacing converters to actively compensate harmonics so paper enhanced a current control approach. The current controllers has two well coupled control branches to independently control the fundamental harmonics DG currents and local non-linear load harmonic current detection, so distribution system harmonic voltage detection are not necessary for proposed method. So closed loop power control scheme is employed to directly derive fundamental current reference without using PLL. The power control eliminates impact of steady state fundamental current tracking errors in DG unit. Harmonic compensation function is active which means accurate power control is realized. This paper is simulated and results are shown below.
