永磁同步风力发电系统的最大功率跟踪模糊分数阶控制OA北大核心CSTPCD

As the the main force of zero-carbon electricity and renewable energy generation,wind power plays a key role in assisting the comprehensive green and low-carbon transforma-tion of society in the context of"dual carbon".It is crucial to maximize the utilization of wind energy and to increase the wind power generation system output while ensuring stable power generation.The maximum power point tracking(MPPT)problem of permanent-magnet synchronous wind power gener-ation system was investigated.Firstly,a mechanism simulation model of permanent-magnet synchronous wind power genera-tion system was established and a two-level dual-PWM full-power converter was used to connect the wind turbine to the grid.Secondly,based on the above model,an integer-order PI controller,fractional-order PIλcontroller and fuzzy fractional-order PI λ controller were designed to implement MPPT con-trol.Finally,simulation research was conducted on the above control strategics.The results show that the fuzzy fractional-or-der PIλ controller has better MPPT performance and better ro-bustness than the other two types,regardless of whether it is in step or random wind speed.
