What this dataset tests
Whether a system can model the baseline coherence structure
of wide-area grid synchronization.
It treats the grid as a coupled phase system
across geographic regions.
Inputs
- average frequency and variance
- phase angle spread between regions
- intertie loading
- load stress
- reactive reserve
- inertia proxy
Required outputs
- regional_phase_coherence_index
- cross_region_sync_strength
- baseline_stability_margin
- drift_rate
- stress_localization
Use case
Layer 1 of COH-GRID-001
Grid Frequency Synchronization Decoupling.
Why it matters
Wide-area blackouts do not start with a trip.
They start when regions stop staying in phase.
This dataset defines what “in phase” looks like
under normal and stressed operation.
