Comparison between MPPTs for PV systems using P&O and Grey Wolf controllers

Abstract

Photovoltaic (PV) systems have recently come to be recognized as the most promising renewable energy source. Due to the photovoltaic generator’s dependence on solar radiation, temperature, and electrical charges, a common issue is that PV system has relatively low conversion efficiency. Solutions based on Maximum Power Point Tracking (MPPT) technologies can increase this efficiency. Utilizing a variety of Maximum Power Point (MPP) technologies, the duty cycle of the DC-DC converter connecting a load and a PV generator can be controlled. Due to their ease of use and low implementation costs, the traditional P& O algorithms were discussed and contrasted with a modern technique named grey wolf optimization (GWO) which demonstrated outstanding performance in maintaining an accurate results while greatly reducing the tracking time to find the precise MPP. Add to lowering the fluctuation inherent in P& O method.
