Grey Wolf Optimization and Fed Fast Terminal Sliding Mode Controllers Based on Interleaved Boost Converters for Symmetric PV Systems under Asymmetric Partial Shading

This research articles proposes a comparative symmetric examination of the four maximum-power point-tracking algorithms under partial shaded conditions, including Conservative MPPT, Grey Wolf Optimization, and Fast Terminal Sliding Mode MPPT. In addition, genetic algorithm particle-swarm optimization perturb observe MPPT are included in this study. A smart method was to use Optimization partly shadowed situations on global study GWO methodology that successfully set efficient FTSM controller parameters such photovoltaic (PV) device monitored shading. MATLAB setting test performance, it programmed for suggested changing shade pattern status dynamically. The findings were assessed compared with other algorithms. Unlike algorithms, used herein wasa less accurate way monitor MPP. These methods also evaluated contrasted PV arrays various shadowing circumstances. experimental investigations verify control techniques stability analysis based asymmetric nonlinear load closed-loop design.
