Wind turbine curtailment via ROSCO

[lorenzoschena]

Hello there,

I was wondering if it is possible to employ ROSCO for power curtailment purposes.

A first, naive, way to tune the controller to this end might be to modify the V_rated of the turbine model to be used? Is there any drawback that you can see in this approach?

If yes, can you please point me in the right direction?

Many thanks,

Hi,

Modifying v_rated in the tuning_yaml will not actually help you de-rate. v_rated is used to separate the range of wind speeds used in the automated tuning process. It's a common misunderstanding about the input we should probably clarify better.

I would change the rated_rotor_speed and/or rated_power. Together, those will determine the rated torque, and the ROSCO tuning process should figure out the proper gains and set points from that.

I hope this helps.

Best, Dan

I'm going to convert this to a discussion because it's not really an issue with the code, but perhaps others would like to contribute or learn more.
