Grid Tie PV Inverter Using Buck-Boost Based Converter Maximizing Power Yield in Mismatched Environmental Condition Controlling Two Solar PV Arrays

Renewable energy is a future of electricity generation in coming years. Photovoltaic generation is being clean method always at the center of renewable energy generation practices in India. Despite of the high cost of installation and lower efficiency, still solar is one of the trusted sources of electricity generation due to its better availability over the year and being clean method of electricity generation. Grid connected solar systems are common now a days so, need to improve different technologies to maximize power yield from solar arrays. The problems related with grid connected PV system are generation of variable voltage and less efficiency. Buck and boost converter-based system is use to produce constant voltage and increase efficiency due to this it will reduce PV modules for grid connection of multiple solar arrays. Buck-boost converter-based system for grid connection of multiple solar arrays is implemented and presented in paper. Authors have proposed maximizing power yield in mismatched environmental condition controlling two solar PV arrays is implemented and presented in this paper in simulation environment by MATLABR2016a Simulink tool. The simulation results for the same are presented in this paper for two solar arrays.
