Development of a Global Maximum Power Point Tracker for Photovoltaic Module Arrays Based on the Idols Algorithm

Mathematics
The main objective of this paper is to develop a maximum power point tracker (MPPT) for a photovoltaic module array (PVMA) under conditions of partial shading and sudden changes in solar irradiance. PVMAs exhibit nonlinear characteristics with respect to

Maximum power point tracking in partially shaded photovoltaic systems using grasshopper optimization algorithm

IET Renewable Power Generation, 2023
The P–V curve of photovoltaic (PV) arrays has several peaks under partial shading conditions (PSCs). Therefore, to extract maximum power, it is necessary to detect its global maximum power point (GMPP). The conventional maximum power point tracking (MPPT)
