Design of Single-phase Photovoltaic Inverter Based on Double Closed-loop PI and Quasi-PR Control

The modeling and simulation on MATLAB/Simulink of a single-phase photovoltaic inverter based on double closed-loop PI and quasi-PR control is studied by this thesis. The state space averaging method is used to construct the mathematical model of single-phase photovoltaic inverter. On the basis of the double closed-loop control strategy, the PI controller is used for the current control of the inner loop, and the quasi-PR controller is used for the outer loop control of the voltage. A simulation model was established. The output results verify that the inverter with this control strategy has perfect comprehensive performances such as a rapid dynamic response character and low total harmonic distortion of output voltage.
