Cheaper Dummy Imports for selected UC

[Lukas]

Dear all,
is there a way how to define cheaper dummy imports just for selected UC? My idea is, that if the mission target is not feasible, the user constraints setting this target will not be fully fulfilled and the remaining part to the target will be satisfied by the negative dummy variable from the dummy import. Currently, the mission target is met only by dummy imports of energy.

I have tried to introduce negative FLO_Cost for the UC, but it does not generate any record. 

Thank you

Just to confirm, you want to introduce a negative flo_cost for the dummy commodities that relax UCs, so that they are imported before energy commodities.

See the example on sheet "all bio for elc" in the scenario "demo_UCs" of this model: https://github.com/kanors-emr/Model_Demo_Adv_Veda.git

Yes, that is what I want. Thank you. But, I am not able to make it work. Probably due to different magnitudes of the commodities.

I face a strange problem to me: Although the scenario (see LST file, please) has Normal Completion with an optimal solution, it does not meet the UC on GHG emission (GHGnetZero2050, dd file attached). GHG is defined via COM_AGG attribute and aggregates other emissions. Could this cause such a problem?
Do you have any advice, please?

In case it might be of any help, I note the listing file shows that you have:

**** 0 ERROR(S)  13833 WARNING(S)

These warnings are domain violations. That's really a lot of them, and they include 'GHGnetZero2050'.
So the easy conclusion is that your constraint is ignored due to the domain violation.

Explaining why you have all these domain violations would require VEDA expertise, and so I'm leaving that to others.
