Harnessing Energy from Solar PV-Wind Hybrids with Vertical Helical Savonius Turbines for Steady Power
摘要
This research paper presents the development and performance evaluation of a Solar PV-Wind Hybrid system designed to revolutionize energy generation in Sri Lanka by integrating vertical helical Savonius wind turbines. The system is engineered to provide reliable and consistent power across various energy sectors, even under fluctuating weather conditions. A 100 W vertical axis wind turbine (VAWT) of the helical Savonius type, coupled with a 100 W Solar PV array and a Pulse Width Modulation (PWM) hybrid controller, feeds into a 24V DC bus for energy storage. The design is optimized by incorporating vertical helical Savonius turbines, known for their enhanced performance in low to moderate wind speeds, and pitched Solar PV panels, achieving a daily energy generation of 0.75 kWh. The research emphasizes the synergistic integration of wind and solar energy, enhancing the overall efficiency and reliability of the hybrid system. Detailed simulations and real-world testing demonstrated the potential of the vertical helical Savonius turbines to maximize energy capture, while the solar panels consistently performed throughout the day. The hybrid system effectively leverages the complementary nature of solar and wind resources, particularly in regions where both are abundant, ensuring consistent energy output even amid environmental fluctuation0s.The study concludes that the Solar PV-Wind Hybrid system, enhanced with vertical helical Savonius turbines and optimized solar panels, offers a robust and sustainable solution to address energy reliability challenges. This innovative approach to hybrid renewable energy systems provides valuable insights into improving energy security and sustainability, particularly in areas with variable weather patterns. Furthermore, the system’s design opens the door to impressive arrays of turbines integrated with solar PV panels for broader applications.
