Abstract
With the continuous growth of global demand for clean energy, wind power generation, as an important renewable energy technology, has become a research hotspot to improve its operating efficiency and power generation. In wind power systems, the maximum power point tracking (MPPT) algorithm is one of the key technologies, which can ensure that the wind turbine always operates in the optimal state under different wind speed conditions, so as to maximize the energy capture efficiency. In this paper, the maximum power point tracking algorithm of wind power system is deeply discussed, aiming to improve the overall performance and economic benefit of wind power system by optimizing the algorithm design. This paper summarizes the basic principle and structure of wind power system, and analyzes the main factors that affect the output power of wind turbine, including wind speed, wind turbine speed, generator efficiency, etc. On this basis, the importance of maximum power point tracking algorithm and its application in wind power generation system are described in detail. In this paper, the principle, characteristics and application effects of various maximum power point tracking algorithms are studied. Among them, the optimal power curve control method based on power signal feedback, adaptive adjustment strategy based on mountain climbing search method, and wind speed tracking control based on tip velocity ratio method are included. These algorithms have their own advantages and disadvantages and are suitable for different wind power system scenarios. In this paper, these algorithms are compared and analyzed, and the advantages and limitations of each algorithm are pointed out, which provides a theoretical basis for the subsequent algorithm optimization. In terms of algorithm optimization, this paper presents a compound MPPT algorithm based on fuzzy logic and intelligent control. The algorithm combines the flexibility of fuzzy logic and the high efficiency of intelligent control, and can dynamically adjust the control strategy according to the real-time wind speed, wind wheel speed and other parameters to achieve more accurate maximum power point tracking. The simulation results show that the proposed algorithm has significant advantages in improving the output power, reducing the fluctuation rate and enhancing the stability of the wind power system. This paper summarizes the research progress and achievements of maximum power point tracking algorithm for wind power generation system, and looks forward to the future research direction. With the continuous development of wind power generation technology and the improvement of intelligent level, the maximum power point tracking algorithm will be continuously optimized and improved to provide strong support for the efficient operation and sustainable development of wind power generation system.
