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.
