Abstract: A method for determining improved control parameters of a number of wind turbines of a wind park is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The method includes the steps of: receiving, by an interface, one or more actual manufacturing tolerances of characteristic values for each of the number of wind turbines; determining, by a processing unit, for each of the number of wind turbines a power versus wind speed map which is calculated from a given turbine model with the one or more actual manufacturing tolerances of the respective wind turbines as input parameters; and deriving, by the processing unit, the control parameters for each of the number of wind turbines from their associated power versus wind speed map.

Abstract: A method for computer-implemented maximization of annual energy production of several wind turbines of a wind park is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The method includes: receiving, by an interface, one or more actual manufacturing tolerances of characteristic values for each of the number of wind turbines; determining, by a processing unit, for each of the number of wind turbines a power versus wind speed map which is calculated from a given turbine model with the one or more actual manufacturing tolerances of the respective wind turbines as input parameters; determine, based on the power versus wind speed map of each of the number of wind turbines a respective performance measure; and assign a selected siting position for each wind turbine in the wind park according to its determined performance measure.

Abstract: A method for determining improved control parameters of a turbine by consideration of a lifetime information is provided. The method considers the impact of individual turbine manufacturing tolerances on the turbine performance, thereby avoiding under-utilization of those wind turbines. The invention includes the steps of: receiving, by an interface, actual operation parameters of the turbine and/or ambient condition information; determining, by a processing unit, a lifetime information about a residual lifetime of the turbine or a turbine component by a simulation of the operation of the turbine, the simulation being made with a given turbine model in which the actual operation parameters of the turbine and/or ambient condition information and one or more characteristic values of the turbine are used as input parameters; and deriving, by the processing unit, the control parameters for the turbine from lifetime information.

Abstract: A method for computer-implemented determination of control parameters of a turbine in case of a component malfunction is provided. The method considers the impact of individual turbine characteristic values on the turbine performance in a turbine model in order to determine control parameters for the turbine without damaging it. The following includes the steps of: receiving, by an interface, an information indicating a component malfunction; identifying, by a processing unit, as to what power level the turbine is operated at, by a simulation of the operation of the turbine, the simulation being made with a given turbine model in which the identified component is set to be operated with a reduced function and in which one or more characteristic values characteristic values of the wind turbine are used as input parameter; and deriving, by the processing unit, the control parameters for the wind turbine from the identified power level.
