As PyPSA-EUR has mostly the same features as PyPSA in general, this provided example will guide the reader through running a simplified model:
- how to configure a (PyPSA-EUR) network model
- how to run snakemake (step by step) from network creation to the fully solved network
- short analysis of the solved network (provided jupyter notebook)
All of the data can be found in /pypsa-eur/example/.
Note
If you were to re-run the example, make sure to take care of the following two arrangement-changes:
- exchange the pypsa-eur/cutouts/europe-2013-era5 folder by the provided one in pypsa-eur/example/europe-2013-era5
- exchange the pypsa-eur/config.yaml file by the provided pypsa-eur/example/config.yaml
You can also rename the original files before pasting the examplary cutout and configuration which will make it easier to switch back after the example.
Configuration
All references in this section relate to the config.yaml provided for this example unless mentioned otherwise. We discuss only major changes to the provided default configuration or point out important settings, as the full discussion of configuration would be too extensive.
Our model example considers only Germany (from all the european countries)
System Message: ERROR/3 (<stdin>, line 33)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml :emphasize-lines: 0 countries: ['DE']
for the duration of only a single month (03.2013):
System Message: ERROR/3 (<stdin>, line 40)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml
:emphasize-lines: 0
snapshots:
start: "2013-03-01"
end: "2013-04-01"
closed: 'left' #end is not inclusive
As we consider a huge cutout (in comparison to whole europe), we should also adapt the CO2-Limit:
System Message: ERROR/3 (<stdin>, line 50)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml
:emphasize-lines: 0
electricity:
[...]
co2limit: 110.6e+6 #(1/12 DE)
We consider all the available conventional generators
System Message: ERROR/3 (<stdin>, line 59)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml :emphasize-lines: 0 conventional_carriers: [nuclear, oil, CCGT, coal, lignite, geothermal, biomass]
with fixed capacity (data provided by pypsa-eur in /pypsa-eur/resources/powerplants.csv), while an additional expandable carrier steps in whenever there is unmet demand that cannot be covered by included Storage Units:
System Message: ERROR/3 (<stdin>, line 66)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml
:emphasize-lines: 0
electricity:
[...]
extendable_carriers:
Generator: [OCGT]
StorageUnit: [battery, H2]
max_hours:
battery: 6
H2: 168
To include profiles (availability curves) for the variable renewable we restrict to the ERA5 dataset in /pypsa-eur/cutouts/europe-2013-era5/ for the same month (03.2013) as well as the approximate latitude and longitude of Germany:
System Message: ERROR/3 (<stdin>, line 80)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml
:emphasize-lines: 0
atlite:
cutouts:
europe-2013-era5:
xs: [4.,15.]
ys: [56., 46.]
months: [3, 3]
years: [2013, 2013]
System Message: ERROR/3 (<stdin>, line 91)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml
:emphasize-lines: 0
renewable:
[...]
solar:
cutout: europe-2013-era5
This last step is insignificant (should not be carried out when running any snakerule) as this example provides the necessary cutout.
Finally, the solver is adapted to cbc, as gurobi might not be free of charge:
System Message: ERROR/3 (<stdin>, line 104)
Error in "code-block" directive: unknown option: "emphasize-lines".
.. code-block:: yaml

Note
For this configuration it might be necessary to install the package ipopt:
conda install -c conda-forge ipopt
All the other configuration parameters remain default.
Snakemake
In order to obtain the resulting network (which also is provided, but try to recunstruct it yourself), open a terminal (or use the shell in EMACS), activate the pypsa-eur environment (activate pypsa-eur) and run:
snakemake results/networks/elec_s_10_lvopt_Co2L-3H.nc
where the final solved network can be now found in pypsa-eur/results/networks with the name elec_s_10_lvopt_Co2L-3H.nc. Each of the intermediate stages is also saved (which we will not discuss here in detail - for more information, see [reference Section] Rules Overview) in pypsa-eur/networks:
base.nc:
Contains the basic network with buses, links and lines.
elec.nc:
Adds electricity to the network, such as generators (individual carriers with their respective capacities), loads and availability profiles for each individual carrier (all of the previous located at the corresponding buses)
elec_s.nc:
Simplifies the previous network (e.g. aggregates generators of same type within one bus)
elec_s_10.nc:
Clusters the previous network to a smaller one with only 10 buses. The previous contained 333 buses.
elec_s_10_lvopt_Co2L-3H.nc:
Reduces the time resulution of the network from hourly to every 3 hours and includes the option to optimive line volumes (lvopt) for the solver.
Short Analysis of the German Network (Jupyter)
Open the jupyter notebook pypsa-eur_example.ipynb and consider buses as well as the timeseries for dispatch.
