Checks for foreign network eGon100RE

[CarlosEpia]

Here will be shared all the comments and checks regarding the foreign countries network. A comparison with the pypsa_eur results will be used. From the pypsa_eur results, only components that belong to these countries are shown: "AT", "CH", "CZ", "PL", "SE", "NO", "DK", "GB", "NL", "BE", "FR" and "LU".

[CarlosEpia]

Regarding buses we have:

Shouldn't we have Li_ion buses?

[CarlosEpia]

Regarding links we have:

• Shouldn't we have BEV_charger?
• I will take a look on the other missing links since some of them are aggregated or deleted intentionally:
  -- CH4 links between foreign countries are missing. @lenzim97 could be the case that they get deleted during the creation of CH4 or H2 grids in Germany?
  --

[CarlosEpia]

Regarding generators we have:

• Only urban_decentral_solar_thermal is missing, but it is intentionally discarded in drop_urban_decentral_heat()

[CarlosEpia]

Regarding storage_units:

• Everything looks OK.

[CarlosEpia]

Regarding stores we have:

• Shouldn't we have battery_storage?

[CarlosEpia]

Regarding loads we have:

• Shouldn't we have land_transport_EV?
• central_heat and rural_heat are suppose to be there in the next run. Fixed in false - run-status2019-and-egon100re-DE #403

[CarlosEpia]

From this point time-series data will be analysed. Since there are several tables for each kind of element, the comparison is presented in a table with multiindex: [table_name, carrier_name] and the values for the columns count-eGon100 and count-pypsa_eur correspond to how many columns of the same carrier there are in the table mentioned in the index.

Empty tables are ignored.

[CarlosEpia]

Regarding link time-series:

• There are no time-series for any link. It is supposed to be fixed in false - run-status2019-and-egon100re-DE #403

[CarlosEpia]

Regarding storage_units time-series:

• Looks OK

[CarlosEpia]

Regarding stores time-series:

• Do we need e_min_pu values for battery_storage?

[CarlosEpia]

Regarding load time-series:

• rural_heat and central_heat are supposed to be fixed in the next run
• Land_transport_EV should be checked.

[ClaraBuettner]

Yes we should have all components modelling the mobility sector ("Li ion" buses, "land_transport_EV" loads, "BEV_charger" links, "battery_storage" stores) and all time series related to these.

I am quite sure that these have been there after the neigbour_reduction task, since I once aligned the carrier names.
So I guess it is again the problem that these components are deleted by another task.

[ClaraBuettner]

@CarlosEpia: I did not take a look at all the images but at your questions.

Regarding the missing links when comparing eGon100RE vs pypsa_eur results:

@ClaraBuettner do we agree that there is a problem related to the CH4 and central_gas_boiler links?

[ClaraBuettner]

When there are no central_gas_boilers and CH4 pipelines in foreign countries it is a problem, yes.

[CarlosEpia]

The problem with the CH4 links is here:

powerd-data/src/egon/data/datasets/gas_grid.py

Lines 878 to 884 in 1a3130d

	# Clean db
	db.execute_sql(
	f"""DELETE FROM grid.egon_etrago_link
	WHERE "carrier" = '{gas_carrier}'
	AND scn_name = '{scn_name}';
	"""
	)

Both pipelines already executed that task. @ClaraBuettner and @lenzim97 does it make sense for you to stop one of the runs to include the changes regarding this problem and start it again?

[CarlosEpia]

The problem with the central_gas_boilers links in foreign countries is here:

powerd-data/src/egon/data/datasets/heat_etrago/__init__.py

Lines 429 to 436 in 1a3130d

	db.execute_sql(
	f"""
	DELETE FROM {targets['heat_links']['schema']}.
	{targets['heat_links']['table']}
	WHERE carrier LIKE '%central_gas_boiler%'
	AND scn_name = '{scenario}'
	"""
	)
