Analysis of Hybrid PV Configurations to Mitigate Partial Shading Losses

Abstract


In photovoltaic arrays, partial shadowing is the predominant issue. It has serious repercussions, including several maxima in electrical characteristics, hot spots on photovoltaic modules, disturbances in tracking maximum power, and diminished output power. During the majority of shadowing situations, the shade is concentrated in one section of the Photovoltaic (PV) array. This shade lowers the efficiency of the PV array. Combining PV modules in diverse configurations is one of the viable strategies for mitigating this issue. In this work, five hybrid configurations are analysed in the MATLAB/Simulink software. Each configuration's array voltage, array current, and array power values at each interval of bypass diode operation were calculated theoretically, and then compared with simulation results throughout a wide range of shade intensities.
