Design of a Global Maximum Power Point Tracking (GMPPT) for PV array based on precise PV shadow model [PDF]

2018 7th International Conference on Renewable Energy Research and Applications (ICRERA), 2018
This paper presents the modeling of a photovoltaic system under complex shading conditions. The approach integrates a complete PV array with each cell modeled separately including shadow coefficients depending on a percentage of area impacted and the level of irradiance (named shaded opacity).

A novel global FPPT strategy for PV system under partial shading condition

IET Renewable Power Generation, Volume 17, Issue 14, Page 3403-3423, 26 October 2023., 2023
Based on statistical results (more than 2430 MATLAB simulations and hard‐in‐loop experiments) with a comprehensive comparison index, the CPA is selected and modified to serve as the core optimizer for the GFPPT optimization problem. Based on the features of MH and GFPP, a novel modification strategy is proposed to reduce searching time, including an ...
