Configuration#

PyPSA-Eur has several configuration options which are documented in this section and are collected in a config/config.yaml file. This file defines deviations from the default configuration (config/config.default.yaml); confer installation instructions at Handling Configuration Files.

Top-level configuration#

“Private” refers to local, machine-specific settings or data meant for personal use, not to be shared. “Remote” indicates the address of a server used for data exchange, often for clusters and data pushing/pulling.

run#

It is common conduct to analyse energy system optimisation models for multiple scenarios for a variety of reasons, e.g. assessing their sensitivity towards changing the temporal and/or geographical resolution or investigating how investment changes as more ambitious greenhouse-gas emission reduction targets are applied.

The run section is used for running and storing scenarios with different configurations which are not covered by Wildcards. It determines the path at which resources, networks and results are stored. Therefore the user can run different configurations within the same directory. If a run with a non-empty name should use cutouts shared across runs, set shared_cutouts to true.

Unit

Values

Description

In order to be taken account, run: scenarios has to be set to true and run: name has to be a subset of top level keys given in the scenario file. In order to automatically create a scenario.yaml file based on a combination of settings, alter and use the config/create_scenarios.py script in the config directory.

scenario#

The scenario section is an extraordinary section of the config file that is strongly connected to the Wildcards and is designed to facilitate running multiple scenarios through a single command

# for electricity-only studies
snakemake -call solve_elec_networks

# for sector-coupling studies
snakemake -call solve_sector_networks

For each wildcard, a list of values is provided. The rule solve_all_elec_networks will trigger the rules for creating results/networks/elec_s{simpl}_{clusters}_ec_l{ll}_{opts}.nc for all combinations of the provided wildcard values as defined by Python’s itertools.product(…) function that snakemake’s expand(…) function uses.

An exemplary dependency graph (starting from the simplification rules) then looks like this:
