Dashboard

Interactive dashboard for this case: start it from the repo root with python tools/hope_dashboard/app.py, then open http://127.0.0.1:8050/ in your browser. The dashboard is pinned to the finalized reference output through ModelCases/ISONE_PCM_250bus_case/dashboard_output.txt, which currently points to output_nocarbon_check.

Current Build Summary

This case is a public-data hybrid ISO-NE-like nodal PCM case built on a synthetic 250-bus New England backbone.

• Network source:
  • TAMU EPIGRIDS Summer90Tight New England 250-bus MATPOWER case
• Load source:
  • public July 2024 ISO-NE nodal load weights
  • public EIA balancing-authority hourly demand for the ISO-NE load zones
• VRE source:
  • public July 2024 ISO-NE hourly wind and solar production chronology from EIA balancing-authority data
  • shaped at plant level using EIA-860 wind and solar attributes
• Fleet source:
  • EIA-860 operable generators for CT / ME / MA / NH / RI / VT
• Storage source:
  • EIA-860 operable storage plus pumped-storage generators converted to explicit storage

Geography and Mapping Notes

• Bus_id is the operating geography for nodal PCM.
• State is retained at the bus level for future nodal policy accounting.
• Zone_id is currently used mainly as a higher-level grouping layer.
• The dashboard map is not official ISO-NE GIS data.
• The current coordinates are built from:
  • electrical partitioning
  • public city / load-center anchors
  • public load-zone corridor pulls
  • optional OSM transmission substations and high-voltage corridor samples
  • public plant-coordinate blending

Validation Snapshot

• High-spread July hours are concentrated around:
  • 188, 189, 212, 237, 236
• Repeatedly binding constraints are concentrated in:
  • internal ROP corridors
  • selected SENE corridors
  • a clearer coastal / southern NNE pocket
  • a more visible NNE to ROP interface path
• Persistent basis separation is strongest on:
  • 136 vs 104
  • 136 vs 164
  • 136 vs 28
  • 136 vs 77
• The case is now suitable for:
  • dashboard-based congestion exploration
  • bus-to-bus basis analysis
  • nodal dispatch and congestion-driver study

Storage Assumptions

• Battery storage uses public EIA-860 power and energy values where available.
• Pumped hydro is modeled as explicit long-duration storage:
  • Northfield Mountain: 7.5 hours
  • Bear Swamp: 3028 MWh
  • Rocky River (CT): 8-hour fallback

Policy Note

• The finalized demo settings keep the first-pass state RPS inputs but disable the carbon cap (carbon_policy: 0).
• This is intentional: the current state carbon-cap inputs were binding enough to force excess NI and load shedding in the July 2024 test case, so the no-carbon settings are the cleaner default example.

Current Limitations

• The 250-bus transmission network is still synthetic.
• Generator-to-bus placement is public-data-informed, but not a market replication model.
• Northern corridor realism can still be improved further, especially for Maine-facing stress.
