Modified Beta Algorithm for GMPPT and Partial Shading Detection in Photovoltaic Systems [PDF]

IEEE Transactions on Power Electronics, 2018
When the photovoltaic (PV) string is under the partial shading condition (PSC), the conventional maximum power point tracking (MPPT) techniques may fail to track the global maximum power point (GMPP). Although some global MPPT (GMPPT) techniques have been proposed, they may overlook the GMPP and fail to detect the PSC occurrence.

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 ...

A novel power-increment based GMPPT algorithm for PV arrays under partial shading conditions [PDF]

Solar Energy, 2018
Abstract Due to dust, structural interfering from surrounding buildings or trees, partial shading conditions (PSCs) are frequently occurred in photovoltaic (PV) arrays, which affects the generated power and system reliability significantly. Under PSCs, PV arrays exhibit multiple local maximum power points (LMPPs), which make the conventional maximum ...
