Abstract

This study introduces a versatile grid-connected hybrid generation system designed to optimize the utilization of renewable energy sources, specifically wind and solar power. The system is engineered to supply power from these sources individually or simultaneously, depending on their availability. For wind energy, a Permanent Magnet Synchronous Generator coupled with a wind turbine regulates the mechanical output. Meanwhile, solar power generation depends on the operating voltage of the solar cells. The DC outputs from these renewable sources are seamlessly converted into AC power by an inverter, making it usable for the connected load. The system operates under typical room temperatures for solar energy and standard wind speeds in plain areas for wind energy. Its efficiency and robustness are further enhanced by a fuzzy-based Pulse Width Modulation (PWM) system, which effectively reduces harmonic ripples, thereby ensuring the delivery of high-quality AC power to the load. Comprehensive simulation results validate the system's operational principles, demonstrating its feasibility and reliability. This hybrid setup not only maximizes the utilization of renewable energy sources but also ensures a consistent and high-quality power supply, highlighting its potential for sustainable energy integration in modern power grids.
