Issue connected to #133 (constraints) and #223, #222 (KPI).
@ursulaelmir can you outline the definition for the net-zero energy constraint so that I can copy and paste it into an .rst file when I create the PR? Also we make sure that way that I am inplementing what you had in mind. I was thinking of:
\sum E_{feedin, DSO, i} - E_{consumption, DSO, i} >= 0
This could be calculated per energy vector and/or for the whole system. What is your take?
Also, there are two ways to implement the co2 emission evaluation:
(1) Add it as oemof-solph inbuild parameter emissions
to each of our assets in D2
, which enables us to easily add an emission_limit
for a constraint on CO2 emissions
(2) Add CO2 emissions as a post-processing KPI that is only calculated from our annual energy flows.
@smartie2076 the definition for net zero energy building or community says that the building or community produces enough renewable energy to meet its own annual energy demand. @SabineHaas could you maybe elaborate on the definition that you have defined for the GRECO project?
Most economic KPI are now displayed in the report. They can also be found in the json file (end of file).
The renewable share does not have a benchmark test, but a unit test.
@ursulaelmir please let me know if the report works for you for sector-coupled systems!
@ursulaelmir I think it would be best to leave the CO2 emissions at the side for now. You can calculate the emissions yourself easily with the DSO and gas/diesel consumption, but it would be quite elaborate to add the calculation to the MVS.
Regarding the weighting factor for heat: I would probably just go with 1 kWh_therm ~ 1 kWh_eleq ~ 1 kWh_el
for now, as anything else would be hard to cite right now. If you find anything on this, it can be easily changed (also quickly after your 90% deadline).
hi @smartie2076 , just a tiny note that I would like to review later on regarding the RE share for hydrogen in my current simulations. When the electrolyzer installed capacity is 0 and optimisation is run, the RE share for hydrogen is 10 and when the pre-installed capacity is 100, the RE share for hydrogen is 0 while only the electrolyzer is being used and the reformer is not used at all. Is it because it is a pre-installed capacity and the RE share is calculated on the optimisation capacities?

Uh-ohhh... No, that should definitely not happen. RE share is calculated from the total flows of the assets, not the capacities, so the resulting share for the same capacity (pre-installed + additional) should be equal. Also, 10 seems a bit weird, eventhough I suppose RE share could be > 1 as there is a transformer efficiency in between the electricity and H2 bus...
can you upload the input folders on the server and send me a link to them?

@ursulaelmir this is exactly how we define NZE buildings/communities. Or as expressed further above in a formula:
\sum E{feedin, DSO, i} - E{consumption, DSO, i} >= 0
The requirements for finishing @ursulaelmir´s thesis were met. Other todos are now managed in #592
