Improving the Dynamic Performance of Hybrid Storage Systems Provided by PV Solar Panels

Solar energy is a clean, renewable resource receiving much attention as a competitive alternative to conventional energy sources. The subject of this study is the integration of rechargeable batteries, supercapacitors, and photovoltaic panels into a hybrid storage system. These parts work together to improve system performance and overcome the shortcomings of individual technologies. Supercapacitors' high power density and fast charge-discharge times enhance the energy density of rechargeable batteries. The battery's lifespan is increased, and adding a supercapacitor enhances the system's overall dynamic performance. The supercapacitor improves the operating conditions of batteries and photovoltaic panels by buffering current variations. The DC-DC converter design and the selection of the maximum power point tracking (MPPT) algorithm significantly impact the system's performance. This study examines the performance of several DC-DC converters, such as the boost and Super-lift Luo converters, and analyzes several MPPT techniques. The supercapacitor is essential when determining which combination suits a given set of operating conditions. An energy management system has been designed to synchronize the charging and discharging of the PV panels, supercapacitor, and battery. Optimal power flow and practical energy storage are ensured by a bidirectional DC-DC converter controlled by a fractional-order proportional-integral-derivative controller. The simulation results show that the Super-lift Luo converter outperforms the boost converter in terms of efficiency and power delivery. The perturbation-and-observation algorithm produces a peak power output of about 980 watts by efficiently tracking the PV panels' highest power point. The energy management system efficiently balances the energy distribution between the battery, supercapacitor, and load to ensure optimal system functioning. This study demonstrates how hybrid storage devices can effectively capture solar energy. A viable way to address the growing need for clean, sustainable energy is to combine the benefits of PV panels, supercapacitors, and rechargeable batteries. It is evident that when utilizing a super lift Luo, the battery's state of charge is approximately 0.2% greater than when using a boost converter. Additionally, super lift Luo is higher for supercapacitors, reaching 0.4% more significantly than a boost converter. The battery and supercapacitor can be charged faster and more efficiently due to the higher.......
