PyPSA-Eur 0.2.0 (8th June 2020)

    The optimization is now performed using the pyomo=False setting in the pypsa.lopf.network_lopf(). This speeds up the solving process significantly and consumes much less memory. The inclusion of additional constraints were adjusted to the new implementation. They are all passed to the network_lopf() function via the extra_functionality argument. The rule trace_solve_network was integrated into the rule solve_network and can be activated via configuration with solving: options: track_iterations: true. The charging and discharging capacities of batteries modelled as store-link combination are now coupled (#116).

    An updated extract of the ENTSO-E Transmission System Map (including Malta) was added to the repository using the GridKit tool. This tool has been updated to retrieve up-to-date map extracts using a single script. The update extract features 5322 buses, 6574 lines, 46 links. (#118).

    Added FSFE REUSE compliant license information. Documentation now licensed under CC-BY-4.0 (#160).

    Added a 30 minute video introduction and a 20 minute video tutorial

    Networks now store a color and a nicely formatted name for each carrier, accessible via n.carrier['color'] and n.carrier['nice_name'] (networks after elec.nc).

    Added an option to skip iterative solving usually performed to update the line impedances of expanded lines at solving: options: skip_iterations; .

    snakemake rules for retrieving cutouts and the natura raster can now be disabled independently from their respective rules to build them; via config.*yaml (#136).

    Removed the id column for custom power plants in data/custom_powerplants.csv to avoid custom power plants with conflicting ids getting attached to the wrong bus (#131).

    Add option renewables: {carrier}: keep_all_available_areas:  to use all availabe weather cells for renewable profile and potential generation. The default ignores weather cells where only less than 1 MW can be installed (#150).

    Added a function _helpers.load_network() which loads a network with overridden components specified in snakemake.config['override_components'] (#128).

    Bugfix in base_network which now finds all closest links, not only the first entry (#143).

    Bugfix in cluster_network which now skips recalculation of link parameters if there are no links (#149).

    Added information on pull requests to contribution guidelines (#151).

    Improved documentation on open-source solver setup and added usage warnings.

    Updated conda environment regarding pypsa, pyproj, gurobi, lxml. This release requires PyPSA v0.17.0.

PyPSA Version 0.16.0
Hyperlinked release notes can be found here:This is the first release of PyPSA-Eur, a model of the European power system at the transmission network level. Recent changes include:

    Documentation on installation, workflows and configuration settings is now available online at pypsa-eur.readthedocs.io (#65).

    The conda environment files were updated and extended (#81).

    The power plant database was updated with extensive filtering options via pandas.query functionality (#84 and #94).

    Continuous integration testing with Travis CI is now included for Linux, Mac and Windows (#82).

    Data dependencies were moved to zenodo and are now versioned (#60).

    Data dependencies are now retrieved directly from within the snakemake workflow (#86).

    Emission prices can be added to marginal costs of generators through the keyworks Ep in the {opts} wildcard (#100).

    An option is introduced to add extendable nuclear power plants to the network (#98).

    Focus weights can now be specified for particular countries for the network clustering, which allows to set a proportion of the total number of clusters for particular countries (#87).

    A new rule add_extra_components allows to add additional components to the network only after clustering. It is thereby possible to model storage units (e.g. battery and hydrogen) in more detail via a combination of Store, Link and Bus elements (#97).

    Hydrogen pipelines (including cost assumptions) can now be added alongside clustered network connections in the rule add_extra_components . Set electricity: extendable_carriers: Link: [H2 pipeline] and ensure hydrogen storage is modelled as a Store. This is a first simplified stage (#108).

    Logfiles for all rules of the snakemake workflow are now written in the folder log/ (#102).

    The new function _helpers.mock_snakemake creates a snakemake object which mimics the actual snakemake object produced by workflow by parsing the Snakefile and setting all paths for inputs, outputs, and logs. This allows running all scripts within a (I)python terminal (or just by calling python <script-name>) and thereby facilitates developing and debugging scripts significantly (#107).
