- To enhance the power quality in distributed generation (DG) systems even under distorted grid, a high performance current control scheme of a grid-connected inverter is presented. The proposed scheme is achieved through the model decomposition of inverter voltage equations into the fundamental and harmonic components. Based on the derived models, the harmonic components are regulated by the predictive control approach to suppress undesired harmonic components quickly. To design the harmonic current controller separately, the harmonic components are extracted through the fourth order band pass filter (BPF). To demonstrate the validity of the proposed current control scheme, a laboratory prototype grid-connected inverter has been constructed using digital signal processor (DSP) TMS320F28335 based controller. The effectiveness of the proposed scheme is proved through comparative simulation and experimental results.
