Abstract
In recent years, renewable energy sources have become more cost-effective than fossil fuels. This research presents a novel hybrid renewable energy system that integrates solar photovoltaic (PV), wind, and hydropower sources with a battery energy storage system (BESS) and a single-phase voltage source inverter (VSI). The proposed system enhances power quality and reliability in single-phase grid applications by providing an effective solution to increase renewable energy penetration and improve grid resilience. A hybrid Boost–Ćuk converter with an improved adaptive sliding mode control-based maximum power point tracking (IASMC-MPPT) technique is proposed to maintain a constant direct current (DC)-link voltage. Furthermore, wind power conversion is improved using a conventional boost converter combined with the Perturb and Observe (P&O) algorithm. The proposed control strategy effectively regulates the single-phase VSI while maintaining microgrid frequency and voltage stability. Additionally, the system mitigates harmonic currents and responds effectively to fluctuating loads by accurately estimating real and reactive power components. Efficient energy management is achieved through the integration of a battery system that regulates energy flow under both surplus and deficit conditions. Simulation results demonstrate that the proposed IASMC-MPPT model outperforms the existing generalized fourth-order filter (GFOF) model, achieving a total harmonic distortion (THD) of 2.14%.
