Maximum Power Point Tracking for Solar Photovoltaic System using Synchronous Reference Frame Theory

Because of its numerous advantages, photovoltaic (PV) electricity is one of the most important renewable energy sources, and obtaining more power from these systems in varying conditions is much needed. Theoretically, simulated, and practically confirmed design of a Maximum Power Point Tracking (MPPT) controller using the Synchronous Reference Frame (SRF) theory is presented in this study. The indirect current control mechanism is used by the system. A solar PV system, a dc-dc boost converter, an MPPT controller, a Voltage Source Converter (VSC), a ripple filter, and a grid make up the whole system. For the simulation of the proposed control scheme, MATLAB / Simulink is used. The simulation results show that the suggested system maintains a high grid power factor under changing load situations, accomplishes voltage management by stabilising it at the Point of Common Coupling (PCC), and offers high grid power under changing load conditions. The suggested technique was also put to the test through an experimental implementation. The findings show that the system is extremely stable, with overall harmonic distortion of only 2.34 percent. In comparison to current techniques in the literature, the suggested approach is less complex and has a low computing cost. The suggested design for a new grid-connected solar panel system with improved power quality is thorough and comprehensive.
