Global Hybrid Maximum Power Point Tracking for PV Modules Based on a Double-Diode Model

IEEE Access, 2021
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
