In some cases, in networks with DC links, a non-existing column would
be referenced in an empty Dataframe. This commit adds a check for this
case.

Recently ICE vehicles were added, but the emissions were not accounted
for. Now, like aviation emissions, they are added as a negative load
to the "co2 atmosphere" bus.
The heat output from the carbon capture (CC) was being subtracted from
the CHP rather than the heat input.
Since the heat output and heat input are the same in the DEA
technology database (but at different temperatures), this bug has no
consequence, but still better to correct it.
Reasoning: we can also have fossil and biomass liquid hydrocarbons, as
well as production from the Fischer-Tropsch process, particularly for
simulations before 2050.
This substitutes the previous way of doing it. Now, to multiply the reference p_nom_max by 3, one should include in the config file 'solar+p3' (instead of the previous solarx3)
For the myopic method, based on the carbon budget indicated in the config file (sector_opts), a CO2 limit is calculated for every planning_horizon following an exponential or beta decay. A file with CO2 limit in every planning_horizon and a plot showing historical and planned CO2 emissions
are saved in the results
**This requires updating to UNFCCC_v23.csv in the data bundle**
This enables that the same function is used to read emissions in 2018, which are assumed to remain constant in 2019 and 2020 and subtracted from carbon budget (estimated from 2018 on).
I checked and 1990 emissions calculated with UNFCCC_v23 are very similar to those calculated with UNFCCC_v21 (<1% differences in all values at EU level).
Some countries show higher deviations, mainly in domestic aviation and navigation. I guess because those values started to be reported later and v23 should include more accurate values.
Running the rule solve_network in the university cluster, I was getting a "No space left on device" error. Making solve_dir=tmpdir by default avoids this error and makes it easier to identify any problem with temp files
This was breaking add_existing_baseyear.py and it is now fixed. Column name for commissioning year in powerplantmatching has changed. Now "DataIn" is used as column name, also when renewable capacities per country are added to the power plants dataframe
* Update prepare_network.py
The new ATK wildcard removes all lines + links without further distinction; however, since storage options are now modeled as store components, the links to and from the the storage units for (dis)charge are eliminated as well. Thus, the storage options drop out of the optimisation.
Especially when only allowing renewables as generation sources, optimisation may become infeasible for a high temporal resolution (capacity factors = 0 for certain hours; no further options to serve the load).
This issue does not arise with the ATKc wildcard, since bus0 and bus1 of the (dis)charge links share the same country code.
The proposed change is a very quick fix in the enforce_autarky function, solely removing DC links.

This is almost a direct copy PyPSA-Eur #167https://github.com/PyPSA/pypsa-eur/pull/167
A factor altering the maximum capacity (p_nom_max) can also be specified by e.g. solar+p3
One should be careful when using this for solar because the factor is applied to all the generators whose carrier includes the string 'solar' (i.e., it is applied to both utility and rooftop solar)
I would suggest implementing 'solar utility' and 'solar rooftop' as carriers, since this can be useful for other selecting processes. Is there is any reason for keeping 'solar' as a carrier for 'solar utility'?
The previous way of increasing maximum capacity via the config file (e.g 'solar3') is still present in the code.
