Sliding Mode Control for Hybrid PV/Wind System Integrated to Power Grids

This paper presents an advanced control strategy for integration of hybrid solar PV and wind energy systems into power networks, utilizing a Sliding Mode Controller (SMC) to address power fluctuations and improve grid stability. Renewable energy sources inherently suffer from environmental uncertainties, leading to intermittent power output and challenges in maintaining power quality. The proposed SMC approach offers a robust and dynamic response to these uncertainties, ensuring effective regulation of power flow and voltage levels within the system. By minimizing Total Harmonic Distortion (THD) and suppressing voltage oscillations in the DC link, the controller enhances the smooth delivery of power to the grid. Real-time simulations are performed to assess the performance of the SMC in comparison with conventional control methods. Results demonstrate a significant improvement in system reliability, reduced harmonic content, and enhanced dynamic stability across various operating conditions. The study highlights the effectiveness of SMC in supporting the reliable incorporation of hybrid renewable systems into modern power grids while maintaining high power quality and operational efficiency.
