Abstract
Wind power generation, as a crucial component of renewable energy, has played a key role in the global energy structure transition in recent years, while power electronics technology holds an irreplaceable position in enhancing the performance and efficiency of wind power systems. This paper focuses on the application and optimization of power electronics technology in wind power generation systems, aiming to address issues such as low energy conversion efficiency, poor grid-connected stability, and complex control strategies in traditional wind power systems. By analyzing the characteristics of different types of wind generators and integrating advanced power electronic converter topologies, an optimized strategy based on model predictive control is proposed, which can significantly improve the dynamic response speed and steady-state accuracy of the system. Meanwhile, in response to potential problems of harmonic distortion and power fluctuation during wind power grid connection, an adaptive filtering algorithm is designed, effectively reducing the impact on power quality at the grid side. Experimental results indicate that the proposed optimization method not only enhances the overall efficiency of the wind power system but also strengthens its adaptability under complex operating conditions. The main innovation of this paper lies in the combination of model predictive control and adaptive filtering technology, providing a new solution for the efficient operation of wind power systems and contributing significantly to the development of wind power generation technology.
