Power Harvested Maximization for Solar Photovoltaic Energy System Under Static and Dynamic Conditions

Applied Sciences, Год журнала: 2025, Номер 15(8), С. 4486 - 4486

Опубликована: Апрель 18, 2025

Photovoltaic (PV) systems are increasingly recognized as a viable renewable energy source due to their clean, abundant, silent, and environmentally friendly nature. However, efficiency is significantly influenced by environmental conditions, necessitating advanced control strategies ensure optimal power extraction. This study aims enhance the performance of PV developing evaluating maximum point tracking (MPPT) algorithms capable operating effectively under both uniform irradiance partial shading conditions (PSCs). Specifically, two metaheuristic algorithms—Particle Swarm Optimization (PSO) Cuckoo Search (CSO)—are modeled, implemented, tested for global peak (GPP) in various static dynamic scenarios. Simulation results indicate that accurately efficiently track GPP PSCs. Under while PSO CSO can initially locate GPP, they fail maintain accurate during subsequent intervals. Notably, exhibits reduced oscillations faster response time compared with PSO. These findings suggest MPPT methods effective environments, remains challenge requiring further enhancement.

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.
