In this paper, a discrete Fourier transform (DFT) based compensation task sharing method is proposed for the improvement of power quality of main grid. Power quality problem induced by typical nonlinear loads is tackled by the cooperation of multi-functional grid-tied inverters (MFGTIs) with the compensation instruction as part of its reference. Unlink the ordinary method where communication is avoided, Low-bandwidth channel is used to transmit the compensation reference after the current data are calculated by DFT. Simulation results are presented to demonstrate the effectiveness of the proposed method.
