I am trying to model the European energy-system using the euro-calliope model. In my project I will run a model in planning mode, followed by a run in "operate mode" with the capacity obtained by the planning run.
Unfortunately I am running into a pretty annoying issue when trying to run the model in operation mode. The model does not run, as it is unfeasible. Saving the model as a .lp file, I discovered that the issue comes from this biofuel constraint in Italy:
I don't know why 2058 is the constraint here, it is zero for all other timesteps of this technology and all other loc_techs.
If I remove biofuel from Italy, the constraint of biofuel in Slovenia (which was 0 when biofuel was allowed in Italy) changes and makes the model unfeasible again. This time the constraint making the model unfeasible is:
After removing biofuel from Slovenia, however, the model runs and produces an output.
My first thought was that there seems to be an issue with the biofuel technology class or the way I link the constraints to the planning part of the model. But there is still biofuel capacity in other countries which is used in the operation mode and all links between the two models are automized, so the way constraints are implemented must be exactly the same for Italy and Slovenia compared to other locations.
I hope I described my issue in an comprehensible way, if not please let me know.
Is this issue familiar to anyone? Does anyone know were I could change anything to not run into this problem?
I am very confused, because there are 34 locations and around 14 technologies that work and the issue only arises at these two instances.
I would be incredibly grateful if anyone could give me a hint what is going wrong!
Hi, I have another question if somebody could help. Is it possible to force a technology to supply or convert the carrier in specific time (for example during the night) ?
@FAYDI yes, that's possible, particularly for supply techs. You could, for instance, set the resource of the technology as a time series (rather than 'inf', if you have a dispatchable supply plant). The time series should then have: resource = a very high value, or inf, during daylight hours; resource = 0 otherwise
