Storage representation

I can see most of your storage processes being input-based, see the table below listing the NCAP_AFC commodity for each hydrogen storage in that model:

                                                    IN         OUT
HYGN_IND_DEC_STG_cap.HYGNINDDECcapts              0.900
HYGN_IND_STG_mer    .HYGNINDDECmerts                          0.900
HYGNINDTRMmer       .HYGNINDDECmerts              0.700
HYGNSTG1MOBDECEN    .HYGNfc1MOBDECEN              0.900
HYGNSTG1INDCENPL_new.HYGNINDCENts_new                         0.900
PIPELINEINDCENPL_new.HYGNINDCENts_new             0.700
HYGNSTG1MOBCENPL_new.HYGNfc1ts1MOBCENPL_new       0.900
HYGNSTG2MOBCENPL_new.HYGNfc2ts2MOBCENPL_new       0.900
PIPELINEMOBCENPL_new.HYGNfs1tplMOBCENPL_new       0.700
HYGNSTG1MOBCEN_new  .HYGNfc1MOBCENTT_new          0.900
TUBETRAILERSTG      .HYGNttMOBCENTT_new           0.900

I think question 1) is up to the modeller to analyse.  Concerning question 2), I can see that you are defining only ANNUAL level NCAP_AFC for these processes.  That means that you will automatically have also CAPACT equations for the process timeslices (DAYNITE), limiting the storage level (activity) by the same capacity.  The default NCAP_AF is 1 for these equations, and that corresponds to a maximum storage level of one day's maximum nominal output. See the documentation for details.

Dear Antti,

I thought I was modelling this as output based. I do not understand how I differentiate input based and output based in VEDA. For example, If you see in the attached base year template, I have kept NCAP_AFC as 0.9 and 0.7 for HYGN_IND_STG_mer and HYGNINDTRMmer respectively in a similar way. But as you shown, one is taken as input based and other is output based. How can I differentiate it in VEDA?

Regarding the storage activity restricition, as you told, If I keep NCAP_AFC as 0.2, this means maximum storage level is 0.2 times the maximum nominal output of one day, right?

What is the difference between defining ANNUAL level NCAP_AFC and DAYNITE level NCAP_AFC? What advantage I will get if I define it in DAYNITE level?
