A Bayesian Multiobjective Approach Based on GMPPT for PV Arrays
International Transactions on Electrical Energy Systems, 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.

A Firework-Based GMPPT with Variable Sampling Time for PV Systems [PDF]
Mathematical Problems in Engineering, 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).

GMPPT approach for photovoltaic systems under partial shading conditions using a genetic algorithm [PDF]
International Journal of Power Electronics and Drive Systems (IJPEDS), 2022 In this paper a new global maximum power point tracking (GMPPT) approach is proposed for a photovoltaic (PV) module using a genetic algorithm (GA) system under partial shading conditions. The partial shading condition is one of the adverse phenomena that the PV system experiences, it is difficult to track true peaks because of existence of multiple ...

Advancing Grid-Connected Renewable Generation Systems [PDF]
Applied Sciences, 2021 If we look at the history of renewable energy sources (RESs), how it all began, and how rapidly they continue to develop, it can be argued that one of the main reasons is due to the rapid improvements in power electronics technology in interfacing the ...

Chaos Quantum-Behaved Cat Swarm Optimization Algorithm and Its Application in the PV MPPT. [PDF]
Comput Intell Neurosci, 2017 Cat Swarm Optimization (CSO) algorithm was put forward in 2006. Despite a faster convergence speed compared with Particle Swarm Optimization (PSO) algorithm, the application of CSO is greatly limited by the drawback of “premature convergence,” that is, the possibility of trapping in local optimum when dealing with nonlinear optimization problem with a ...
