Chaos Quantum-Behaved Cat Swarm Optimization Algorithm and Its Application in the PV MPPT. [PDF]
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 ...

GMPPT approach for photovoltaic systems under partial shading conditions using a genetic algorithm [PDF]
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

Global Hybrid Maximum Power Point Tracking for PV Modules Based on a Double-Diode Model
Photovoltaic systems under partial shading conditions (PSC) need to operate at the global maximum power point (GMPP) to extract the maximum possible power. Partial shading is characterized by the exhibition of a multi-peaked behavior in the voltage power

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