Model modifications

To better match client needs, various modifications have been added to PyPSA-Eur. To implement this, two approaches have been considered :

1. when feasible, the request is generalized and submitted to the community as pull request (see Submitted pull requests) ;

2. if not, a custom modification is added to the model (see Custom modifications).

Submitted pull requests

Here is the list of pull requests shared with the community. Depending on the pull request, the modification has been integrated or not to the official repository of PyPSA-Eur.

Custom modifications

When no suitable for a pull request, the customisation is added on our fork of the model. Techno-economic assumptions have been thoroughly reviewed as described in Techno-economic parameters.

• Add project specific configurations ;

• Develop a Streamlit app available at https://climact-veka-2050plus.streamlit.app/ ;

• Develop a data management pipeline to produce files required by the app ;

• Define a set of configurations and techno-economic assumptions, needed for scenario management ;

• Add custom configuration to model Flanders as a node ;

• Add custom configuration to model nuclear powerplants ;

• Fix PV shares in Belgium to reflect current imbalance between regions ;

• Split HVC primary route into three types of routes (NSC, NSC CC and MTO) to include VLAIO scenarios for Flanders ;

• Split DRI route of steel in two routes (DRI CH4 and DRI H2), needed for scenario management of industry. DRI CH4 is model using MIDREX process ;

• Fix BEV dsm restriction time to take time aggregation and time zones into account ;

• Add emission prices for each planning horizon ;

• Update IRENA data to 2023 ;

• Update status of TYNDP links to the latest version available ;

• Limit offshore wind capacity in Belgium to a realistic value ;

• Add a proxy to model distribution costs of gas boilers ;

• Update OCGT, CCGT and coal CC efficiencies to include electricity demand of CC ;

• Add CC and H2 gas turbines ;

• Add hydrogen import terminals ;

• Add a marginal costs for gas and hydrogen pipelines to model operating costs ;

• Add a rule to produce map with capacities ;

• Add a rule to manage multiple set of costs, needed for scenario management ;

• Generalize agg_p_nom_minmax constraint to handle nuclear and all types of offshore wind ;

• Fix config provider to work as expected with reference scenario ;

• Stick to version 0.5.11 of PyPSA/powerplantmatching to ensure stability ;

• Fix various minor issues.
