Abstract: A method for controlling noise generated by a wind farm with a plurality of wind turbines is disclosed. In the event that a predicted noise level exceeds a predefined threshold noise value, one or more wind turbines are selected using a noise propagation model and respective wind turbine models for the selected one or more wind turbines, and by performing an optimisation process to reduce the predicted noise level at the predefined evaluation position to a level below the predefined threshold noise value while maximising the total power production of the wind farm.

Abstract: Aspects of the present invention relate to a method for determining annual energy production of a wind farm. The method comprises: receiving a definition of the wind farm; modelling the wind field of the wind farm for a plurality of freestream wind speeds in a plurality of wind directions; defining 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 a wind farm blockage factor for each freestream wind speed in each wind direction based on data from the virtual measurement masts; receiving measurements from a physical measurement mast located at the site of the wind farm; and determining 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.
