MATLAB Based MPPT Optimization for Enhancing PV System Performance under Partial Shading Conditions (KEY IJP************278)

Abstract

Partial shading in PV systems significantly reduces performance by introducing multiple local maxima in the voltage current characteristics, leading to power loss and decreased efficiency. While traditional methods such as bypass diodes and MPPT aim to mitigate these effects, they often fall short, especially under complex or dynamic shading conditions. This paper presents a novel approach using optimization algorithms to address the impact of partial shading in PV systems. The proposed method utilizes simulation models to predict and identify shading patterns, with optimization techniques dynamically adjusting the systems configuration and operating points to maximize power output. The approach is validated through MATLAB simulations, incorporating irradiance, temperature, and shading data to train the models. Simulation results show significant improvements in energy conversion efficiency compared to conventional methods, with faster adaptation to changing shading conditions. The paper also discusses the advantages and challenges of implementing optimization-based strategies for real-time PV monitoring and control.
