I suppose you want to calculate a diagram for previsions based on the power of the wind of a determibate zone. If it is this your problem, to taste the zone in base of the power of the wind and to calculate the amount of energy there are 2 kinds of ALGORTHMS:
1)NEURAL ALGORTM
2) PHYSICAL ALGORITHM
that are based on :
- Meteo wrf Forecast
- Historic wind data
- Ground description
You can find it on site of GSE (www.gse.it) /Delibera ARG
But it's in Italian Language.
In we we can open a discussion after I have studied well the question.
