Research on Bi-Directional Grid-Connected Inverter Based on PI Regulator and Compensation Control
This paper establishes current control model of grid-connected inverter in synchronous rotating frame. Based on the model, a new control strategy which is combined with PI regulation, decoupling, and feed-forward compensation is proposed. Software algorithms are designed in this paper. Based on TMS320LF2407A and IPM Module PM50RLA12, experimental platform for grid-connected inverter is built. Experimental waveforms are given in the paper.
