ADVANCING PV SYSTEM EFFICIENCY THROUGH INTEGRATED SOLAR CONCENTRATION AND FORECAST BASED MPPT CONTROL

An adaptive control design for maximum power point tracking (MPPT) in a photovoltaic system (PV) is presented in this study. MPPT techniques are employed in the PV system to provide the load with the most power possible in the face of variations in ambient temperature and solar radiation. A novel method called concentrated photovoltaics (CPV) aims to increase the efficient utilization of solar energy. Because they can absorb a lot of solar energy, photovoltaic solar cells are growing in popularity. However, their widespread application is hindered by PV solar cells' higher initial costs and relatively lower conversion efficiency when compared to other non-renewable energy sources. CPV technology employs optical devices to concentrate solar energy into a smaller area of solar cells in order to maximize solar-to-thermal conversion. This aids in getting around these limitations. The primary advantages of CPV systems are their great efficiency, affordability, and environmental sustainability. This paper also examines the challenges associated with CPV system implementation, the factors influencing their performance, and the latest developments. Although CPV systems typically have efficiency levels of up to 15%, some advanced designs have shown efficiencies as high as 25–28%. There is still significant room for improvement, even though current research indicates that CPV efficiency may reach up to 38.5% at optimal solar radiation levels. One of the challenges with CPV technology is the potential increase in solar cell temperature caused by concentrated sunlight. The longevity and electrical efficiency of the system may suffer as a result. Scientists have looked at a variety of cooling techniques for effective temperature IJ2026V6I6 The state-of-the-art methods, incremental conductance (INC) and perturb & observe (P&O), are compared using MATLAB/Simulink under different operating circumstances based on convergence time, tracking efficiency, PV current & voltage ripple, overall efficiency, and error rates.
