Abstract: An advanced power control strategy by limiting the maximum feed-in power of PV systems has been proposed, which can ensure a fast and smooth transition between maximum power point tracking with Partial Power Converter (PPC)[6] and Synchronous Reference Frame (SRF) method. Regardless of the solar irradiance levels, high-performance and stable operation are always achieved by the proposed control strategy. It can regulate the PV output power according to any set-point and force the PV systems to operate at the left side of the maximum power point without stability problems. The effectiveness of the proposed PPC control[3] in terms of high accuracy, fast dynamics, and stable transitions improvement. Overall power management unit is controlled by the converter & control loop. Performance analysis (power & stability) [10] of the overall system is carried out using MATLAB/SIMULINK model.
