FLORIDyn (OFF toolbox) Code and input files underlying the publication: Wind pattern clustering of high frequent field measurements for dynamic wind farm flow control

Python implementation of the FLORIDyn code [1] in the OFF toolbox, as well as the input files used for the publication "Wind pattern clustering of high frequent field measurements for dynamic wind farm flow control", M Becker, D Allaerts and JW van Wingerden, in preparation for the TORQUE 2024 conference.

The yaml files contain the baseline orientation (misalignment angle = 0 deg) and optimised angles. The C1 to C5 addition in the name refers to the wind direction change case that is investigated. The optimised angles have beed derived using FLORIS [2] and are given in separate files for convenience.

To run the code FLORIS [2] needs to be installed. In addition the DTU 10MW reference turbine [3] is used in the simulations. The required .yaml is provided with this code and needs to be added to the FLORIS turbine library. Go to 03_Code/main.py and run the selected case.

The farm power of all simulations in FLORIDyn in given in the files FarmPower*.csv

To use them in Matlab, call:

farm_pow = readmatrix("FarmPowerNoYaw.csv");

farm_pow = reshape(farm_pow, 5, length(1:2:359), [] );

Dimension 1 is along the cases, dimension 2 along the wind directions and dimension 3 along time (4:4:2000).

E.g. to plot the power for case C4 starting at 201deg call

plot(4:4:2000, farm_pow(4, (201+1)/2, :))
