Dear Antti,
I am a fresh user of TIMES models (although, have some GAMS modelling experience) from IVL, Sweden.
Currently, I am trying to figure out how to represent a seasonal thermal energy storage in one of our models.
I improved greatly my understanding of the storage modelling approach by reading the Documentation Part II file and by following your replies here: https://iea-etsap.org/forum/showthread.php?tid=168&highlight=storage
However, there are two issues/questions I would still like to clarify:
1) If I model a seasonal energy storage and I know that losses are 0.18 %/day, is it correct to define the STG_LOSS attribute as follows:
STG_LOSS = 0.18 * 365 / 100
2) A bit trickier issue - I would like to account for electricity consumption that occurs during the operation of a storage. I have tried to account for the consumption using a FLO_FUNC attribute ( in a way shown in the attached Excel file) but obviously have done it wrongly since the model run is terminated (LST file is also attached).
May I ask you to look into the attached files and tell me how to fix this issue with Auxiliary flows in/our storage processes.
Looking forward to hearing from you.
Have a great day,
Dmytro
