Modified Synchronous Reference Controller for Three-Phase Inverter
摘要
In this article, a modified synchronous reference function is presented for managing the grid-tied photovoltaic system’s interface inverter to reduce harmonics. The suggested approach also incorporates a PI controller to reduce steady-state inaccuracy. It has the effect of maintaining a consistent voltage level at the common DC point. The MSRF is made to analyze three-phase reference currents by taking the basic elements out of load current and grid voltage levels. The proposed MSRF offers several benefits, including improved boosted renewable energy sources’ ability to respond, variable phase and frequency, grid alignment, and minimal computational load on the MATLAB platform.
