Changing the bounds of the yaw optimisation

[henrysanders3]

Hi all,

I am having trouble altering the bounds of the yaw optimisation. I believe i have been through all of the input files and functions (e.g.yaw_optimizer_sr) to change the minimum and maximum yaw angles, however when I run the code it still optmises between 0 and 25 degrees. Where in the FLORIS files do i need to make changes to amend this?

Can the minimums and maximums be overwritten in the code?

Thanks in advance

Hi Henry,

I think I might be having the same problems as you, I am trying to alter the bounds to -25 to 25 degrees to analyse the optimal yaw angles. After altering all of the floris files it still optimise between -25 and 25 degrees. IS there a way this can be overwritten in the code?

Thanks

@rafmudaf Do you know how to fix this?

thanks

Hi. Here's what the current main branch gives with the example 10_opt_yaw_single_ws.py:

Note that the default optimization bounds are 0 deg and +25 deg. The figure above shows optimal yaw angles between these limits. Then, if you want to change your optimization limits, you can change lines 43-44 to:

yaw_opt = YawOptimizationSR(fi, minimum_yaw_angle=-30.0, maximum_yaw_angle=30.0)
df_opt = yaw_opt.optimize()

and the result is:

Generally, you should never change the default choices in the FLORIS classes to change the options for one particular case. You should always do this on the script side, like above.

@Bartdoekemeijer That works, thank you very much! Is there a way the rotor diameter can be overwritten in a similar way? Many thaks

@henrysanders3 Let's keep that conversation in #595.
