Import AEP values from another software was created by Victor Mendoza
Hello everyone, 
I am learning to use PySAM. My goal is to run a wind energy project cost estimation PPA & single owner. I have my own code for AEP and uncertainties.

My questions are:
- What are the input values needed in the financial model from the wind/wake/aep module?
- How can I introduce my own input values instead of using the ones calculated with the PySAM wind power performance model? (I have tried wp.Outputs.annual_energy = "my own AEP value", but of course it does not work) Is there any example available for this?
- Where in  github.com/NREL/ssc can I find the wake combination/superposition model? (aiming to understand discrepancies with my own model)
- Where in  github.com/NREL/ssc can I find the uncertainty calculations? (aiming to understand discrepancies with my own model)

Your support is highly appreciated in advance!

Hi Victor,

Regarding performance model outputs that are inputs to the financial model, and using your own AEP data, see my reply to your post at sam.nrel.gov/forum/forum-sdk/4841-import-aep-values-from-own-tool.html .

The source code for the wind wake models is here: github.com/NREL/ssc/blob/develop/shared/lib_windwakemodel.cpp

You can find publications describing SAM's wind power model here: sam.nrel.gov/wind.html

The wind uncertainty calculations implemented in SAM's user interface. I would refer to the Diamiani, R. (2018) paper listed on the Wind Publications page for those equations, but if you want see their implementation in SAM: github.com/NREL/SAM/blob/develop/deploy/runtime/ui/Wind%20Uncertainty.json

Best regards,
Paul.
