Hi,
I couldn't find an attribute defining the UC Multiplier for VAR_FOUT and VAR_FIN. How could I address it especially when I wanna involve STG input and output separately in a constraint? (e.g., battery input ELC and output ELC with energy loss)
Best,
Xiao

The UC multiplier attributes are, in general, directly related to model variables, such as:
● UC_ACT – for VAR_ACT
● UC_FLO – for VAR_FLO
● UC_IRE – for VAR_IRE
● UC_CAP – for VAR_CAP
● UC_NCAP – for VAR_NCAP
● UC_COMNET – for VAR_COMNET
● UC_COMPRD – for VAR_COMPRD
● UC_CUMFLO – for VAR_CUMFLO
● UC_CUMCOM – for VAR_CUMCOM
There are no variables named VAR_FOUT or VAR_FIN, those are
reporting attributes, which have no UC multipliers. TIMES does have the storage-related variables VAR_SIN and VAR_SOUT, but no related UC multipliers ("UC_SIN" / "UC_SOUT") have ever existed in the UC design specifications. However, there is an easy workaround for them, see:
