Abstract

The primary challenge in renewable energy production is the unpredictable nature of renewable sources, leading to inconsistent electricity generation. This variability causes deviations in power supply frequency and voltage due to imbalances between load demand and power generation. This study focuses on regulating power flow in a solar-wind-based Hybrid Power Generating System (HPGS) to achieve a stable balance between energy generation and demand. A Fractional Order PID (FOPID) controller is employed to minimize power fluctuations by ensuring Maximum Power Point Tracking (MPPT) and efficient management of Superconducting Magnetic Energy Storage (SMES). The SMES utilizes a second-generation superconducting material with a high irreversibility field and critical current density, enhancing energy storage efficiency. Compared to a conventional PID controller, the FOPID controller offers greater stability, reduced oscillations and overshoot, and a shorter rise time. To validate its effectiveness, a comparative analysis between conventional PID and FOPID controllers is conducted. The results demonstrate that the proposed FOPID controller ensures precise MPPT, rapid SMES response, and stable power exchange between supply and demand, even during sudden load shifts and variations in power generation.
