Strange Histograms


#1

I have been collecting data directly from the web-app from North Sea locations and I found all of them give a strange power output as you can see below. The locations are in the Dogger Bank area (coordinates: 54.7500N 1.9167W and 54.9902N 4.7900W).
Should the histogram instead show a peak in the low-end power rating and one in the higher-end (caused by cut-in and cut-out speeds)?
Can the output of one specific coordinates in the map be used together with the capacity factors per country from the Renewables Ninja v1.1 data set?



Source: 54.75N 1.9167W, year 2010, Power: 10000kW, Vestas V90 2000 or Siemens SWT 4.0.

According to “I. Staffell and S. Pfenninger, 2016. Using Bias-Corrected Reanalysis to Simulate Current and Future Wind Power Output. Energy, 114, 1224–1239” the power output is smoothed to represent a wind farm with geographically dispersed turbines. Therefore the histograms above represent a wind farm in the North Sea.
When it comes to wind output estimations for annual energy outputs regarding a wide area like a country, one can use their Virtual Wind Farm R code https://github.com/renewables-ninja/vwf.
