Hi all,
I wanted to double check the way i Ma modeling 4hour battery because I am seeing very little storage in the results. I know it may be related to the battery economics but i thought i'd run my modeling by you. Here are my modeling assumptions:
Do these modeling assumptions look reasonable to you?
Thank you
I wanted to double check the way i Ma modeling 4hour battery because I am seeing very little storage in the results. I know it may be related to the battery economics but i thought i'd run my modeling by you. Here are my modeling assumptions:
- Storage efficiency: 85%. I am reflecting this as STG_EFF=0.85 and FLO_FUNC(ELC, AuxStoOUT, ANNUAL) =1/0.85=1.1765
- 4hours of capacity for day night operation. This translates to: AFAC(ELC)= 4/24=0.1667, NCAP_AFC(ACT, DAYNITE)=4/24/0.85=0.1961
- 6hours to full charge. This translates to AFC(NRG, DAYNITE)=4/6=0.67
- Auxstoin and auxstoout are used for some downstream processing
- CapAct is 29.89 because my energy unit is Tbtu
- the constraints shown in the screenshot below are neutral and are used for reporting purposes.
Do these modeling assumptions look reasonable to you?
Thank you
