Abstract: Aspects of the present invention relate to a method (100) for determining annual energy production of a wind farm. The method (100) comprises: receiving (102) a definition of the wind farm; modelling (104) the wind field of the wind farm for a plurality of freestream wind speeds in a plurality of wind directions; defining (110) locations for virtual measurement masts upstream of upstream turbines in each wind direction at a clearance from each upstream turbine for identifying wind farm blockage effects; determining (112) a wind farm blockage factor for each freestream wind speed in each wind direction based on data from the virtual measurement masts; receiving (114) measurements from a physical measurement mast located at the site of the wind farm; and determining (116) an annual energy production for the wind farm based on adjusted wind speeds obtained by applying the blockage factors to measurements from the physical measurement mast.

Abstract: The invention provides a method (100) for determining a wind turbine layout in a wind power plant comprising a plurality of wind turbines (207). The method comprises the steps of generating (101) a plurality of random layout candidates (201-203, 300) fulfilling a set of basic requirements, and then performing a pre-screening process (102) on each of the plurality of random layout candidates (201-203, 300). Based on the pre-screening process (102), a subset of layout candidates is selected (104) and detailed optimization (105) is performed on the layout candidates of the selected subset of layout candidates. Based on the detailed optimization (105), an optimized layout (300) for the wind power plant is selected among the optimized layout candidates of the subset of layout candidates.

Abstract: A method of operating a wind turbine. The wind turbine is operated over an operating period in accordance with a control strategy. A sensor signal is received over the operating period from a sensor measuring an operational parameter of the turbine. A model is used to obtain a modelled fatigue value based on the sensor signal. The modelled fatigue value provides an estimate of fatigue loading applied to a component of the turbine over the operating period. The control strategy is modified based on the modelled fatigue value.
