FSC - MPC for single-stage grid connected PV system.

The single-stage grid-connected photovoltaic (PV) design has lately gained popularity due to its ability to minimize total losses and installation costs. This research describes an unique control strategy for single-stage grid-connected PV systems. The control scheme combines (FSC-MPC) with (P&O) technique to ensure maximum power collection from PV panels. as well as excellent transient performance for output current. The suggested scheme removes the usage of the DC/DC stage, which reduces the losses associated with the inclusion of the boost stage. To estimate the currents under different voltage vectors, an FSC-MPC method is devised; the ideal voltage vector is determined based on the optimal cost function, and the corresponding optimal switching mode being applied to semiconductor switches in the inverter. further Further, the controller was tested in the variation of irradiation. The proposed control system was simulated using MATLAB/SIMULINK environment. The collected findings show that the suggested control strategy ensures MPP tracking and the injecting of extracted PV power into the grid with excellent current quality despite variation in irradiation.
