PyPSA-GB - v2.2.0

PyPSA-GB v2.2.0

PyPSA-GB v2.2.0 adds a major two-stage market dispatch workflow, stronger historical market validation, improved ETYS network upgrade handling, and new tools for renewable aggregation and marginal-cost calibration.

Highlights

• Added two-stage market dispatch:

  • Stage 1 copperplate wholesale market solve.
  • Stage 2 constrained balancing mechanism redispatch.
  • Rolling day-ahead wholesale mode and rolling/per-timestep balancing mode.
  • Optional wholesale-only workflow.
  • Market dashboards, summaries, and generated analysis notebooks.

• Added ELEXON and NESO market validation tooling:

  • ELEXON BMRS bid/offer data retrieval and shared cache handling.
  • BMU-to-generator mapping.
  • ELEXON-derived bid/offer price support.
  • BM calibration scorecards.
  • NESO constraint validation and boundary analysis outputs.

• Improved marginal-cost and subsidy modelling:

  • Daily, thermal, and renewable marginal-cost calibration scripts.
  • CfD and ROC subsidy tracking.
  • Post-solve revenue accounting.
  • Support for empirical renewable marginal costs from ELEXON bid data.

• Improved ETYS network modelling:

  • More robust ETYS upgrade application for circuits, transformers, and HVDC links.
  • ETYS file registry for version-aware file and sheet handling.
  • Better handling of HVDC aliases, coordinates, and network validation.
  • New ETYS network figures for 2023 and 2035.

• Added renewable aggregation:

  • Optional aggregation of renewable generators by bus and carrier.
  • Capacity-preserving aggregation with capacity-weighted p_max_pu profiles.
  • Unit tests covering aggregation behaviour.

• Expanded configuration and scenarios:

  • New market scenario examples.
  • Rolling market validation scenarios.
  • Renewable performance factors.
  • Embedded generation correction options.
  • BM line-rating overrides and voltage-level relaxation settings.

• Documentation updates:

  • New market dispatch user guide.
  • Updated API documentation for market, ETYS, and integration modules.
  • Updated workflow, configuration, scenario, network, and troubleshooting docs.
  • Added market dispatch tutorial.

Testing

This release adds unit coverage for renewable aggregation, BMU mapping, market utilities, connectivity repair, and updates workflow scenario validation tests.

PyPSA-GB - v2.1.0

Demand-Side Flexibility (major new feature)

• Added heat pump flexibility modelling with three modes: TANK (hot water storage), COSY (building thermal mass pre-heating), and MIXED
• Added electric vehicle flexibility modelling with four tariff modes: GO (off-peak), INT (intelligent), V2G (vehicle-to-grid), and MIXED
• Added event response flexibility (demand response during peak windows)
• New orchestration script (add_demand_flexibility.py) integrates all three flexibility types into the Snakemake pipeline
• New support scripts: build_ev_availability.py, build_heat_profiles.py, finalize_demand_integration.py
• Flexibility configuration added to defaults.yaml with per-component enable/disable toggles
• New example scenarios: HT35_flex, HT30_event_response, HT35_year

Cutout Support

• Added Zenodo data download support

Network Clustering and Aggregation

• Added post-clustering component aggregation to reduce memory requirements (aggregate_components.py)
• New aggregate_components config block with toggles for storage units, loads, and stores
• Fixed component clustering issues

Solver and Numerics

• Relaxed default solver tolerances (BarConvTol, FeasibilityTol, OptimalityTol: 1e-5 to 1e-4) for stability with large storage models
• Increased NumericFocus from 2 to 3 (maximum numerical care)
• Added BarIterLimit solver parameter

Marginal Costs

• Added configurable marginal cost defaults for future scenarios (carbon price, fuel prices)
• Support for FES-extracted dynamic prices with fallback to configured defaults
• Tidied marginal cost application logic

ETYS Network

• Modified ETYS network mapping for flexibility integration
• Fixed DUKES carrier assignment
• Improved thermal plant spatial allocation

Carrier Definitions

• Registered 18+ new carriers (heat pump, EV, demand response, thermal, V2G, etc.)

Documentation

• Rebuilt Sphinx docs with updated content for clustering and flexibility features

Other

• Merged sector-coupling PR
• Cutout year now aligns with the selected scenario
• Added various diagnostic and test scripts

PyPSA-GB - v2.0.0

PyPSA-GB v2.0.0

PyPSA-GB v2.0.0 is a major release of the open-source energy system model for Great Britain, designed for high-resolution, scenario-based electricity network analysis. This version features:

• Full support for ETYS (2000+ bus) transmission network, Reduced (32-bus), and Zonal (17-zone) models.
• Automated scenario routing: historical (DUKES, REPD, ESPENI) vs. future (FES, GSP-level, projections).
• Improved renewable and storage integration using FES GSP-level data and REPD patterns.
• Accurate spatial mapping with robust WGS84↔OSGB36 coordinate handling.
• ETYS Appendix B 2023 network upgrades (circuit, transformer, HVDC) with scenario-based filtering.
• Modular Snakemake workflow for reproducible, scalable runs.
• Enhanced debugging, validation, and logging tools.
• Performance optimizations for large networks and time series.

Ideal for researchers, planners, and policymakers modeling GB’s future electricity system.
