With the rapid development of industry, the development and utilization of renewable and clean energy has become crucial for achieving sustainable development. However, the inherent volatility and intermittency of renewable energy sources pose significant challenges to grid stability and energy efficiency. The present study focuses on the characteristics of wind and photovoltaic power generation systems and investigates the principles and mathematical models of windsolar hybrid power generation under the influence of complex meteorological factors. Furthermore, a comparative analysis of maximum power point tracking (MPPT) methods for windsolar power systems is conducted, and simulations are performed to implement MPPT and pitch control for wind turbines. The efficiency and stability of the hybrid system are validated. Additionally, the peak-shaving capability of energy storage devices is utilized to achieve constant power grid connection, significantly enhancing the output stability of the system. This research provides valuable insights for the further efficient utilization of renewable energy.
