Abstract

This Paper presents a comparison of two controlstrategies applied to current controlled inverters in renewableenergy systems. The strategies are the Synchronous ReferenceFrame and Stationary Reference Frame. First control methoduse PI regulators and it is the most used inverters control. Inthis paper, it is shown how to simplify the parameters design ofthe Proportional-Resonant controller for the StationaryReference Frame. This paper presents the grid model anddetailed design and stability analysis with a modified SymmetryCriterion method for the PI regulator parameters calculus. Fromthis point, we transform the designed PI regulator into a PRwhich it's needed for the Stationary Reference Frame Control.Results in terms of THD; indicate the better performance of pRcontrol.
