Preparing Networks

The preparation process of the PyPSA-Eur energy system model consists of a group of snakemake rules which are briefly outlined and explained in detail in the sections below:

build_shapes generates GeoJSON files with shapes of the countries, exclusive economic zones and NUTS3 areas.
build_cutout prepares smaller weather data portions from ERA5 for cutout europe-2013-era5 and SARAH for cutout europe-2013-sarah.

With these and the externally extracted ENTSO-E online map topology (data/entsoegridkit), it can build a base PyPSA network with the following rules:

base_network builds and stores the base network with all buses, HVAC lines and HVDC links, while
build_bus_regions determines Voronoi cells for all substations.

Then the process continues by calculating conventional power plant capacities, potentials, and per-unit availability time series for variable renewable energy carriers and hydro power plants with the following rules:

build_powerplants for today's thermal power plant capacities using powerplantmatching allocating these to the closest substation for each powerplant,
build_renewable_potentials for the installation potentials for solar panels, onshore and offshore wind turbines constrained by landuse restrictions and natural protection areas,
build_renewable_profiles for the hourly capacity factors in each substation's Voronoi cell for PV, onshore and offshore wind, and
build_hydro_profile for the hourly per-unit hydro power availability time series.

The central rule add_electricity then ties all the different data inputs together into a detailed PyPSA network stored in networks/elec.nc.
