Ok, I can see you have managed to get the process E001 working. The crucial mistake I can see in the model is that HYDS is defined as a free renewable. As such, it has no commodity balance, and therefore modeling a storage process for it would be completely meaningless.
But I did not see any indication of a supply process for HYDS; you should create such as well. I would thus suggest that you test your model after doing the following modifications:
- Change the commodity type of HYDS from free renewable to limited renewable (this is crucial)
o You can also remove the superfluous COM_GMAP(REG,NRG,HYDS)
- If you still have no supply process for HYDS, you need to create such now:
o Output = HYDS, PCG=HYDS, no input required
o ANNUAL level
o Set also a reasonable upper bound ACT_BND(UP), for the annual inflow
- I suggest to disable the second storage process (ST0002) for now, because:
o It has no capacity bound / investment costs, and might thus have infinite storage level without any cost impact
o Note also that it is pointless to use NCAP_AFC(ACTGRP) if you are not using NCAP_AFC(output)
