Hi Paul,
I download latest weather data from NSRDB via API and then use wind farm model in matlab to estimate power output, since power curve data of those wind turbines are available on related website and wind farm model is not very complicated. The result is ok. Just remember to transfer wind speed data from 2 m to 100 m height.
(Btw, in wind part reference manual, wind speed is said to be at the height of 10 m, so without your clarification, I won't know they are actually just 2 m height. Thx again for your help.)
Best,
Yanda
