METHODS AND SYSTEMS FOR GENERATING WIND TURBINE CONTROL SCHEDULES

Methods and Systems for Generating Wind Turbine Control Schedules A method of generating a control schedule for a wind turbine is provided, the control schedule indicating how the turbine maximum power level varies over time, the method comprising: determining a value indicative of the current remaining fatigue lifetime of the turbine, or one or more turbine components, based on measured wind turbine site and/or operating data; applying an optimisation function that varies an initial control schedule to determine an optimised control schedule by varying the trade off between energy capture and fatigue life consumed by the turbine or the one or more turbine components until an optimised control schedule is determined, the optimisation including: estimating future fatigue lifetime consumed by the turbine or turbine component over the duration of the varied control schedule based on the current remaining fatigue lifetime and the varied control schedule; and constraining the optimisation of the control schedule according to one or more input constraints; wherein the optimisation further includes varying an initial value for a wind turbine lifetime, and varying an initial value for the number of component replacements, for one or more components, to be performed over the course of the schedule to determine a combination of the number of component replacements for one or more turbine components and a target minimum wind turbine lifetime.
