Dashboard

A live demo is hosted on Hugging Face Spaces:

HOPE PCM Dashboard →

The demo runs the Germany 2-day nodal PCM case with bundled output data — no installation required.

To run locally from the repo root:

python tools/hope_dashboard/app.py

Then open http://127.0.0.1:8050/ in your browser.

Current Build Summary

This Germany build is designed as a comparison-ready PCM case suite:

one canonical Germany nodal master case
one 4-zone Germany zonal derivative case
one solved 2-day nodal demo case for dashboard exploration

The guiding design rule is:

build the nodal case first
freeze geography and chronology mappings once
derive the zonal case mechanically from the nodal master case

Source Stack

Network backbone:
- OSM Europe transmission dataset from Xiong et al. 2025
- PyPSA-Eur workflow used as the main preprocessing reference
Generator fleet:
- powerplantmatching first-pass Germany fleet inventory
- BNetzA MaStR and Kraftwerksliste reserved as validation layers
Chronology:
- SMARD Germany load and actual generation
- four SMARD TSO-area load helper files for 50Hertz, Amprion, TenneT, and TransnetBW
Dashboard zone geometry:
- Germany state-boundary GeoJSON reconstructed into a 4-TSO dashboard overlay

Map note: this is a geography-style nodal network map built from the solved Germany dashboard demo case, with the reconstructed TSO overlay shown behind the nodal transmission network. It is intended as an engineering-style case map, not as an official public TSO GIS rendering.

Current Solved Status

The current full-year Germany zonal derivative case has been assembled and solved.

The current full-year Germany nodal master case has been assembled, but the practical dashboard example is the shorter solved nodal demo case below.

Geography and Mapping Notes

Bus_id is the operating geography for the nodal Germany PCM case.
Zone_id uses four Germany research zones:
- 50Hertz
- Amprion
- TenneT
- TransnetBW
The zonal case is an internal research aggregation for comparison, not the real DE-LU bidding-zone market design.
The Germany dashboard TSO overlay is file-backed and more realistic than bubble polygons, but it is still a reconstructed research layer rather than an official public TSO shapefile.

Integration Workflow

Raw OSM Europe network tables are cleaned into a HOPE-ready Germany network backbone.
A frozen Bus_id -> Zone_id map is created once and reused by both nodal and zonal builds.
The Germany fleet is cleaned from powerplantmatching and each generator is assigned to one nodal bus.
SMARD chronology is normalized once and reused across nodal and zonal builds.
The zonal case is derived by aggregation from the nodal master case rather than calibrated separately.

Validation and Debugging Notes

Initial Germany nodal debug runs exposed:
- disconnected-network issues
- singular-network behavior
- reactance / angle-scaling pathologies
The main fixes were:
- transformer connectivity retention
- keeping the largest connected component
- HOPE-compatible reactance normalization for the DCOPF network
After those fixes, the 1-day and 2-day full-nodal Germany debug cases solved cleanly and the 2-day case became the dashboard default.

Current Limitations

The 4-zone Germany comparison setup is a research zoning, not a market replication model.
The dashboard TSO geometry is reconstructed from real outer geography plus frozen case geography, not from an official control-area GIS layer.
The short solved nodal demo case is dashboard-ready, but longer nodal horizons still need staged solve validation.
Generator validation against MaStR and Kraftwerksliste can still be deepened.
