Stand-alone systems and self-consumption in SAM with the Fuel Cell models

Hello Paul,

I have a query related to the performance and financial models in SAM. I am looking to model systems that are completely isolated or detached from the grid - stand-alone renewable systems. I want to be able to do this with the fuel cell model in SAM.
How do I go about doing this and if these kind of remote systems can be simulated in SAM at all (or does it only work for grid-connected projects)?
For now, if I select commercial distributed generation as the financial model for fuel cells, I am sort of forced to input utility electricity rates and incentives, as they have an impact on the resulting cash flow. Whereas, the kind of system I have in mind would not necessarily need grid connection to function. 

Kind regards,
Vedika 

Hi Vedika,

Please see this post for more on off-grid systems: sam.nrel.gov/forum/forum-general/2960 .

Best regards,
Paul.

Hello Paul,

Thank you very much. I was hoping I would be able to simulate something resembling an isolated system, but it is proving a little tricky. 
On a separate note, I have a question related to the results I get from one of the cases I ran with the fuel cell model. In the tutorials by SAM they showed that we could visualise the PV output power of the system but for the simulation I ran, there is no data that specifically displays PV generated power or electricity to load from PV (reference to two images below - one from the tutorial results and one showing the list of time series data from my test case). Could you maybe give me an idea of why this might be the case? 

Kind regards,
Vedika

Hi Vedika,

The "Electricity to load from system" in the current version of SAM is equivalent to "Electricity to load from PV' in that presentation.

Best regards,
Paul.
