考虑疲劳优化的风电场有功功率调度策略OA

The uneven fatigue distribution of wind turbine units in wind farms leads to problems such as the attenuation of the service life of wind turbine units and high operation and maintenance costs.It proposes an optimal active power scheduling strategy that takes into account the fatigue experienced in wind farms.Firstly,it introduces a fatigue load evaluation model based on spindle torque and tower thrust to reformulate the challenge of optimizing fatigue load distribution into an active power allocation problem.Subsequently,it uses the NSGA-Ⅱ(Non-dominated Sorting Genetic Algorithm)to optimize the reference value for active power distribution across turbines,thereby mitigating cumulative fatigue damage to both the spindle and tower components.Finally,simulation results demon-strate that this proposed approach effectively reduces cumulative fatigue damage in the main shaft and tower of wind turbines,ultimately prolonging their operational life while decreasing associated operation and maintenance costs.
