The integration of supercapacitors into solar energy systems offers a promising approach to overcome the limitations of conventional energy storage technologies. This paper presents an advanced framework for supercapacitor integration aimed at enhancing solar energy. . Electrochemical capacitors, which are commercially called supercapacitors or ultracapacitors, are a family of energy storage devices with remarkably high specific power compared with other electrochemical storage devices. In addition, effective multi-storage power management in a PV system needs a solid grasp of the energy storage technologies, load. . This paper addresses the energy management control problem of solar power generation system by using the data-driven method. The battery-supercapacitor hybrid energy storage system is considered to smooth the power fluctuation. A new model-free control method is utilized in the stand-alone. . . This method promotes energy autonomy, offers operational flexibility, compensates for fluc uations in solar production, and can result in long-term economical savings. It also allows for optimized energy management through efficient storage and redist ibution.
