Powercurve is not accurate above 15m/s.
Today there is an assumption that beyond 15 m/s, the data points are collected into one bin. Hence the flat line behaviour for high wind speeds for the learned power curve.
This is no longer be a fair assumption if wind turbines are operating at increasingly higher wind speeds.
The power curve resolution should be the same all the way up to 25 m/s

We have several turbine models that ramp-down at high wind speeds, and this is becoming increasingly common. Preferably the learned power curve would capture this, so that the theoretical energy and system availability are more accurate

Yes, and sometimes we have derating for high wind speed!
