PV-Battery hybrid system power management based on backstepping control

Résumé

With the increasing global energy consumption and the need for sustainable solutions, this article focuses on the energy management of a hybrid photovoltaic (PV)-battery system using the backstepping method. The research addresses the challenges of intermittent solar irradiation by implementing an incremental conductance maximum power point tracking (MPPT) algorithm for the PV panel and backstepping control for battery charging and discharging. The system's performance and control effectiveness were validated through laboratory experiments. The results demonstrate the system's robustness, stability, and ability to respond to fast changes, making it a promising solution for efficient energy management in hybrid PV-battery systems. The findings provide valuable insights for future research and advancements in this field.
