Abstract
Space weather-induced geomagnetic disturbances (GMDs) drive geomagnetically-induced current (GIC) to flow into electric power networks, causing undesirable effects such as reactive power losses, voltage drop, current and voltage harmonics. A combination of these effects triggered blackouts in the Hydro-Quebec grid in 1989 and the Swedish grid in 2003. Given that the Dominion Energy Virginia (DEV) grid is at moderate risk of GMD due to its location, a system-wide vulnerability study was performed to assess that risk. The work included analyzing harmonic propagation from GIC-aflected transformers to the rest of the system and evaluating the voltage stability margins (VSMs) for various system contingencies during extreme GMD scenarios. Results showed that certain portions of the grid exhibited voltage distortion considerably above acceptable limits, but harmonic screening of grid equipment showed that they are not vulnerable to damage. This work also illustrates the potential of GMDs to reduce VSM and exacerbate system contingencies.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
