Abstract:

 

Proportional plus Resonant controller is presented as the injected grid current regulator applied to a single-phase grid connected inverter. This paper establishes a systematic approach to design the gains of the PR controller by determining its minimum and maximum threshold points, to achieve improved transient and steady-state performance. Extensive simulations are carried out by varying system parameters and their effects on magnitude and bandwidth of the amplitude-frequency response are explained.

Keywords:

 

Current control, resonant controller, Grid-connected
