Yaw Control Of Permanent Magnet Wind Turbine Based On Differential Evolution Algorithm

With the gradual reduction of fossil energy and the erratic global climate,countries all over the world are pursuing energy structure reforms and have introduced a series of effective methods to replace traditional fossil energy with new energy sources.In the 13th Five-Year Plan of China,the important position of environmental protection has been clarified,the proportion of clean energy has been increased,and an energy-efficient and environmentally-friendly and sustainable energy ecosystem has been vigorously developed.As the most mature and commercial-scale clean new energy industry,wind power generation has its unique characteristics of no pollutants and continuous renewable development,which makes it play a pivotal role in new energy and even the entire energy structure.However,due to the irregular characteristics of wind energy,the power generation efficiency of commercial wind turbines currently on the market is not satisfactory,and problems such as low wind precision,slow control response,and prone to false alarms are common.This paper is mainly based on the yaw control of permanent magnet wind turbine based on differential evolution algorithm.Firstly,the composition and working principle of the wind turbine are introduced in detail.Then,based on the wind energy theory,the wind energy utilization limit value is calculated,and the wind speed and wind direction measurement methods are proposed.Then the wind turbine yaw control system model is established to determine the yaw The working principle and control flow of the control system are finally simulated.Finally,the yaw control system model of wind turbine is simulated by MATLAB simulation software.The traditional empirical method PID control,PD control based on differential evolution algorithm to optimize PID parameters,and differential evolution algorithm are compared.Combined with discrete controllers to form the control of the hybrid controller.The simulation results show that the hybrid controller control strategy can effectively improve the execution efficiency of the wind turbine yaw control system,and it is accurate to the wind,reduce unnecessary yaw action during the completion of the wind yaw process,and reduce the yaw execution structure.Mechanical wear between them reduces maintenance and repair costs.
