Firm connected N-1 headroom

Unavailable

The optimized zero-request dispatch already violates a connected N-1 thermal limit; candidate-specific firm headroom is not available.

Exact baseline cut-set certificates

These exact-rational certificates prove specific zero-request transport cut-set deficits under the recorded outages. They do not certify AC feasibility or candidate hosting capacity.

Fast DC/PTDF/LODF screen using RATE_A and generator limits. Recorded preventive-dispatch policy: generator-bounds-constrained preventive dispatch minimizing the worst normal and connected N-1 branch utilization, followed by a strictly convex least-squares tie-break anchored to supplied generator PG. Candidate transfers use bounded proportional generator participation. Redispatch remains idealized within PMIN/PMAX: ramp limits, reserves, costs, and area interchange constraints are not modeled. It also excludes dynamics, protection, constructability, cost, schedule, outage probability, and 3 selected islanding outages. The optional AC badge covers only the snapshots explicitly listed in result.json. “+MVA” is a mathematical rating delta, not a construction design or price. Use this to choose where to study next, not as an interconnection approval.
