Balanced AC power flow
One exact saved snapshot or scenario, with measured bus and branch results.
No implicit N-1 and no independent cross-solver acceptance.
Engineering scope
Know what the run measured.
The admitted extension profiles are bounded, versioned and specific. A green job status is not independent engineering acceptance.
Admitted native profiles
Readiness and data quality
Surfaces missing or unsupported model inputs and parameter provenance.
Does not silently repair imported data or attest a manufacturer source.
Scenario and outage screening
Selected snapshots and branch outages with explicit islanded or failed states.
Bounded steady-state screening, not operational security approval.
Dispatch and loadability
Bounded native studies on exact cases with retained movements, bounds and results.
Sampled limits do not certify capacity or global optimum.
Continuation P–V and AC sensitivity
Versioned curves or local finite-difference load P/Q samples.
Not a proven stability margin, PTDF/LODF or planning approval.
Short circuit and protection
Admitted fault and coordination profiles with explicit source and qualification limits.
Not every upstream protection device or duty method is qualified.
Corrective dispatch has a precise name
Bounded corrective AC work optimizes each selected outage separately and requires an independent AC feasibility check. Failed, islanded or unconverged outcomes remain visible. It is not joint/global SCOPF, a certified optimum or engineering approval.
Keep units explicit
Native load and generator active power use MW, reactive power uses MVAr, voltage setpoint uses per unit, and continuous branch rating uses MVA. Imported units are never guessed into apparent correctness.
