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

open access: yesIET 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)

A Hybrid Maximum Power Point Search Method Using Temperature Measurements in Partial Shading Conditions

open access: yesMetrology and Measurement Systems, 2014
Photovoltaic panels have a non-linear current-voltage characteristics to produce the maximum power at only one point called the maximum power point. In the case of the uniform illumination a single solar panel shows only one maximum power, which is also ...
