A novel hybrid grey wolf optimized fuzzy logic control based photovoltaic water pumping system

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Abstract This paper describes the novel scientific contribution of a modified hybrid grey wolf optimization‐fuzzy logic controller (GWO‐FLC) based on maximum power point tracking (MPPT) for a photovoltaic (PV) system. The modified GWO eliminates the lower rank (δ) and lowest rank (Ψ) wolves, which provides a rapid search method to track global maximum ...
