Wind-turbine wake models are used in the design of wind farms, to optimise the choice of turbine model, and the layout of the turbines. They're also sometimes used in the operation of wind farms, to maximise generation.
What is the evidence on the accuracy of the wind turbine wake models?
I'm primary interested in accuracy with specific regard to maximising windfarm profitability: that is to say, judging their accuracy from the perspective of their objectives when used in wind farm design and operation. If there aren't studies looking at their accuracy with regard to maximising generation at lowest cost, then some other measure of accuracy would be acceptable: at worst, something like root mean square error (as unsatisfactory as it is in this context).
