The branch heat-2023-rebased has some final issues that need to be resolved:
[x] Electric boilers in district heating
[x] Distribution losses of district heating networks
[x] CHP ultra supercritical cofiring coal
[x] CHP local engine mt network gas
[x] Fix Northern Ireland isolation levels when re-exporting the datasets
Electric boilers in district heating
For the electric boiler, the heat output is specified on ETLocal and set to 0 TJ in all datasets. However, no SGQs or graph_methods have been added in ETSource. There are two possible solutions 1) is to remove the data and interface elements for the heat output of electric boilers or 2) to add efficiency of the electric boiler to ETLocal, add SGQS to ETSource to set the demand and efficiency of the boiler, add graph_methods to the nodes and re-export the datasets.
Ideally, we would opt for solution 2, but it seems to be a significantly bigger effort. If this is indeed true, then I would suggest we go for solution 1. However, the issue below also seems to require a re-export of the datasets anyway, so that may mean an efficiency gain for solution 2.
Distribution losses of district heating networks
The distribution losses on ETLocal are specified as loss share. ETSource however only uses the steam hot water share i.e., 1 - the loss share. There are SGQs to determine the steam hot water share based on the loss share. The issue however is that the prefix "input" is missing from the interface elements on ETLocal.
We therefore have to update the distribution loss interface elements to add the prefix "input", migrate the interface elements and (probably) re-export the datasets.
CHP ultra supercritical cofiring coal
The SGQ for the CHP on MT, energy_chp_ultra_supercritical_cofiring_mt_coal+demand, has a spelling error it refers to input_energy_chp_ultra_supercritical_cofiring_ht_coal_production and should refer to input_energy_chp_ultra_supercritical_cofiring_mt_coal_production.
The SGQ should be updated. I'm not sure if the datasets need to be re-exported as well?
CHP local engine mt network gas
This is the exact same issue as for the CHP ultra supercritical cofiring coal.
