Abstract

In view of that PI controller parameters changes when system model parameters of single- phase photovoltaic inverter change, a gradient reference based adaptive current loop control method is proposed. Ignoring the high order harmonics in PWM inverter, the mathematical model of the grid connected system is deduced, the reference model is selected reasonably,me according to the change parameters by using the normalized MIT adaptive law. The grid-connected current has good tracking effect on the instruction current. Control effect is insensitive to the change of the filter parameters, and has fast tracking speed and strong robustness.
