摘要： The invention describes a method for computer-implemented maximization of annual energy production of a number of wind turbines (T1,...,Tn) of a wind park. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The invention comprises the steps of: receiving, by an interface (IF), one or more actual manufacturing tolerances of characteristic values (AG, MP, MDM, TC, CR) for each of the number of wind turbines (T1,...,Tn); determining, by a processing unit (PU), for each of the number of wind turbines (T1,...,Tn) a power versus wind speed map (PWM) which is calculated from a given turbine model (TM) with the one or more actual manufacturing tolerances of the respective wind turbines (T1,...,Tn) as input parameters; determine, based on the power versus wind speed map (PWM) of each of the number of wind turbines (T1,...,Tn) a respective performance measure; and assign a selected siting position for each wind turbine (T1,...,Tn) in the wind park according to its determined performance measure.
