Due to environmental factors' influence, the power–voltage (P–V) curve of a photovoltaic array typically presents multiple peaks. The traditional gravitational search algorithm is inclined fall into local optimal solutions and demonstrates poor performance in maximum power point tracking. Consequently, this paper proposes applying PSO for optimizing GSA parameters. Meanwhile, introducing constant accomplishes dynamic adjustment three key parameters PSO. Furthermore, Levy flight step incorporated enhance global capability. improved can improve speed accuracy by adding memory group interaction particle update formula alleviate oscillation. Simulink modeling simulation analysis reveals that, compared with algorithms, identify more rapidly stably under static shading conditions.
