The Performance Analysis of Wireless Photovoltaic Power Transfer System Under Partial Shading Condition

The primary factor in a photovoltaic (PV) module's operation is solar irradiance. It is possible to link the output voltage of a PV module to a wireless power transfer (WPT) system, also known as a wireless photovoltaic power transfer (WPVPT) system. Numerous studies have looked at the WPVPT system's performance in relation to factors including solar irradiance, the distance between the transmitter and reception coils, the magnetic field, and the voltage produced on the transmitter coil. The impact of partial shadowing on WPVPT performance, however, has not been researched. The study of the WPVPT system under partial shade is therefore the subject of this research. To model and simulate the partial shading situation and WPVPT system, MATLAB SIMULINK is used. It is used on three PV modules that have various levels of solar irradiation. The findings demonstrate that in order to maintain the system frequency of 50 Hz as well as to match the frequencies of the two coils, the inductance of the transmitter and receiver coils of 0.1689 H should be linked in parallel to a capacitor of 60 F. When the WPVPT system is used to replicate the partial shade conditions, PV modules 1, 2, and 3 obtain solar irradiation of 1000 W/m2, 100 W/m2, and 100 W/m2, respectively. With peak AC voltages of 297 V, 279.8 V, and 5.744 A on the receiver coil, respectively, it shows that the output voltage of the three PV modules when linked in series is 177 V. This affects how well the WPVPT system functions.
