A Bayesian Multiobjective Approach Based on GMPPT for PV Arrays

International Transactions on Electrical Energy Systems, Volume 2022, Issue 1, 2022., 2022
This paper considers the problem of tracking the global maximum power point (GMPP) in partially shaded conditions (PSCs) as a multiobjective optimization problem and solves it using a novel multiobjective optimization algorithm on the basis of Bayesian optimization formulation.

Investigation on Photovoltaic Array Modeling and the MPPT Control Method under Partial Shading Conditions

International Journal of Photoenergy, Volume 2021, Issue 1, 2021., 2021
On the basis of a five‐parameter photovoltaic (PV) mathematical model, a multipeak output model of a PV array under partial shading conditions (PSCs) is obtained by MATLAB simulation. Simulation and experimental results demonstrate that the model can simulate the performance curves of the PV array under the PSCs.

A Firework‐Based GMPPT with Variable Sampling Time for PV Systems

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Photovoltaic systems have a nonlinear characteristic in which there is one optimum operating point called Maximum Power Point (MPP). However, when PV panels are partially shaded by surrounding objects, there are several MPPs, of which one of them is Global MPP (GMPP).
