Architecture and 28A blackout simulation, in two scrolls.
How DCF-GRID ingests PMU/SCADA data and produces a predictive horizon. The signals shown are reproduced from the public REE / ENTSO-E / MedFasee technical reports of the 28 April 2025 Iberian blackout — the 0.6 Hz inter-area oscillation, the post-intervention damped phase, the silent drift, the cascade.
Inputs · sealed engine · outputs the operator can act on.
DCF-GRID integrates as a non-intrusive software layer over existing PMU and SCADA environments. The proprietary engine is sealed by design — auditable on request under NDA, never exposed publicly. The signals it consumes and the signals it returns are open and standard.
The 28A as it happened, with the horizon overlay.
PMU/SCADA signals reproduced from the published 28A timeline: 0.6 Hz inter-area oscillation between 12:02 and 12:08, post-intervention damping, silent drift, voltage rise in the southwest, cascade onset at 12:30, frequency collapse at 12:33. The Hp predictive horizon is computed continuously from the same input signals via an illustrative stress-to-time model — actual DCF computation is proprietary under NDA.
