A Fast GMPPT Algorithm Based on PV Characteristic for Partial Shading Conditions [PDF]
Electronics, 2019 Photovoltaic (PV) modules experience some partial shading conditions (PSC) due to some various factors. In that kind of a condition, a few maximum power points (MPPs) possibly appear on the power-voltage (P-V) curve, which increases the tracking difficulties. It is known that maximum power point tracking (MPPT) may not be realized by hill climbing (HC)

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 ...

Implementation and simulation analysis of GMPPT algorithm under partial shadow condition
Energy Procedia, 2019 Abstract Due to partial occlusion, the output power and voltage curves of PV arrays appear multiple peak points, which increase the difficulty of designing the maximum power tracking system. The limitations of the conventional GMPPT method under the partial shadow are analyzed, and the failure of the traditional optimization algorithm is obtained ...

Fast Indirect GMPPT Method for PV Systems under Uniform and Partial Shading Conditions
Nigerian Journal of Technological DevelopmentUnder Partial Shading Conditions (PSCs), conventional MPPT techniques fail to locate the Global Maximum Power Point (GMPP) for PV generators, and when PSCs change suddenly and repetitively, several GMPP tracking techniques takes time to find or miss the
