Autonomous Calculations was created by mzdrillion

Hello,
I've setup my SAM model to represent a PV+Battery system that I want to evaluate for sustaining a critical load (that happens to equal 100% of load during the year). As such, it seems the Autonomous Calculations would provide this output ( samrepo.nrelcloud.org/help/index.html?grid_outage.htm ). However, in running the simulation, SAM is now 'bogged' down (this happened somewhere around 65% simulating progress, if that helps),... the simulation took maybe an hour or two to get in the 60's, but I'm currently at ~86% simulation progress after an additional ~84 hours on my computer, with little end in sight. Is this kind of simulation time expected for my described setup??
Thank you for your help!

Hi Matthew,

A SAM simulation should not take that long -- even with battery dispatch and grid outage calculations over the analysis period, the simulation run time should be on the order of minutes, not hours.

Please attach a copy of your .sam file if you would like me to help troubleshoot.

Best regards,
Paul.

Hi Paul,
I sent the SAM file to This email address is being protected from spambots. You need JavaScript enabled to view it. for your review.

Thank you for your support,
Matthew
