Contour plot of AEP

[Teddybear0227]

I am trying to search for a way to plot a contour diagram visualising the percentage loss of AEP for each turbine in wind farm as shown in the attached image (retrieved from https://iopscience.iop.org/article/10.1088/1742-6596/2265/2/022049/pdf ).

I am thinking of calculating the percentage loss of AEP for each turbine in the following process.

1. using fi.get_turbine_power(), calculate the power produced by each turbine in wind farm
2. multiply the frequency for each wind direction and wind speed, and multiply it by 365.25*24 to get AEP for each turbine

Is there any way to convert such array of AEP into a contour plot.

Sincerely,

Hi @Teddybear0227, we don't have any inbuilt functionality for generating this kind of plot. However, I think you should be able to achieve what you want pretty quickly with matplotlib.pyplot.scatter.

Here's an example that could get you started:

import matplotlib.pyplot as plt
import numpy as np

x = np.array([1, 2, 3, 4, 1, 2, 3, 4])
y = np.array([0, 0, 0, 0, 1, 1, 1, 1])
aep = np.array([100, 90, 80, 70, 90, 80, 70, 60])

fig, ax = plt.subplots(1,1)
sc = ax.scatter(x, y, c=aep, cmap="cividis", vmin=50, vmax=110)
plt.colorbar(sc)

ax.set_xlim([0, 5])
ax.set_ylim([-0.5, 1.5])

plt.show()

which generates

In fact, you'll find some very similar code in example 29_floating_vs_fixedbottom_farm.py, so you could also take a look at that for some more refined plotting code.

Hello @misi9170 !! Thank you very much for the information. The method worked perfectly for me.

Sincerely,
