Release Notes

Upcoming release

This part of documentation collects descriptive release notes to capture the main improvements introduced by developing the model before the next release.

New Features and Major Changes

  • Attach wind and solar generators using real positions from powerplants.csv instead of using redistribution according to the population PR #1622

  • Revise implementation of myopic optimization PR #1722

  • Migrate all cost data processing to process_cost_data.py PR #1719

  • Add the rule retrieve_cutout using the same script from retrieve_databundle_light. The bundle_to_download excludes cutouts while cutout_to_download include only cutouts. The retrieved cutouts are then verified to ensure their total bounds match the outputs from build_shapes. The config enable: retrieve_cutout allows users to switch off this rule after retrieval. PR #1767

  • Use IRENA statistics for 2023 to normalize countries hydropower generation data PR #1681

  • Drop use of override_components that is no longer needed in newer PyPSA versions PR #1699

  • Ensure connectivity of transformers in buses with several transformers PR #1706

  • Enable green-field capacity expansion of custom lines under construction PR #1778

  • Remove unused override_respot PR #1805

  • Integrate DemandCast dataset for electricity demand PR #1725

Minor Changes and bug-fixing

  • Add CI to update reference objective values PR #1811

  • Fix UnboundLocalError and back-pressure RHS leak in add_chp_constraints #1814

  • Add config parameter enable_electricity_connection_cost, which adds electricity grid connection costs to fixed capital costs for solar and onwind generators in prepare_sector_network PR #1810

  • Avoid crash in add_chp_constraints when the network has no links, supporting operational models without brownfield/expandable batteries, pumped storage, or DC links PR #1750
