hello,

I have the wind turbine power results on the left and the wind speed on the right, both varying over a 24-hour period. From three different scenarios, it's clear that the power output doesn't align with the wind speed. Could this be due to the filter I uploaded? If so, how can I modify it?

thank you in advance

@jana nassereddine,

The horizontal axis labels and values are partly cut off, or absent, on the three images you uploaded which contain two plots each. It appears that the horizontal axis labels for the left side plots are "Load (kW)". If that is correct, then the plots are not power versus time. Do the right side plots (with black background) show wind speed versus time? Please plot power versus time and wind speed versus time, with visible labels and units and values, for both axes. Then we will know what is being compared.

The system diagram shows a sampling rate of 1e-6, but the right side plots appear to be sampled much more slowly. Please figure out why this is so, and why the sampling rate appears different for the right and left side plots.

I don't think the lowpass filter is the cause of the mismatch between wind speed and power output, because the power waveform in the plots does not appear to be a lowpassed version of the speed waveform. I suspect the difference is due to the inner workings of the wind turbine power system box, or the difference is because you are not plotting what you mean to be plotting.
