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.

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).
