Hi Ivan,
The Land-based Balance of System Cost Model (LandBOSSE) is a cost model that calculates a balance-of-system (BOS) cost on the Installation Costs page. LandBOSSE is a separate model from the Wind power model.
LandBOSSE has inputs for the interconnect voltage in kV that it uses for the BOS cost calculation because the voltage determines the size and type of equipment required for the interconnection, which affects cost.
The Wind power model calculates the power output of the system in kW based on the power curve on the Wind Turbine page and the wind speed data in the weather file. The wind power model does not have a voltage model, so it does not calculate system voltages.
If you use the LandBOSSE model to calculate BOS costs, you should make sure to choose inputs that are consistent with the system you are modeling. For example, the LandBOSSE model is designed for large-scale utility projects rather than small wind projects, but SAM will not prevent you from using it with a single small turbine.
Best regards,
Paul.
