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:

:mod:`build_shapes` generates GeoJSON files with shapes of the countries, exclusive economic zones and NUTS3 areas.

Unknown interpreted text role "mod".
:mod:`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:

:mod:`base_network` builds and stores the base network with all buses, HVAC lines and HVDC links, while

:mod:`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:

:mod:`build_powerplants` for today's thermal power plant capacities using powerplantmatching allocating these to the closest substation for each powerplant,

:mod:`build_renewable_profiles` for the hourly capacity factors and installation potentials constrained by land-use in each substation's Voronoi cell for PV, onshore and offshore wind, and

:mod:`build_hydro_profile` for the hourly per-unit hydro power availability time series.

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