Hi all,
Firstly, thanks to the NREL team for making and maintaining this important tool. Thanks also to Paul for supporting the community.
As renewables penetration increases, there is more focus on the ability to deliver 'firm' renewable power. (See Google's 24/7 renewables initiative, or the 'Round the Clock' PPA auctions in India). So developers need to determine how to meet a fixed minimum amount of power per period, through a blend of RE plants and storage. This issue has of course been important for off-grid hybrid plants for some time.
I was wondering if SAM's battery model has a dispatch algorithim which maximises reliability. It would be fairly simple behaviour, where the battery would only charge using excess generation after the fixed load is met. And only discharge when the fixed load target is not being met.
I can't see this in SAM, but there's a variable in PySAM which suggests it could be conisdered. (batt_dispatch_charge_only_system_exceeds_load, batt_dispatch_discharge_only_load_exceeds_system).
Thanks for the help with this.
Best regards,
Henry
