20 000 – 70 000 bus systems in under one second — on a laptop.
Kestrel PowerFlow™ is a proprietary, commercial-grade Newton-Raphson engine built from the ground up
for the most demanding transmission studies on the planet.
Hot-Start Capability
Re-solve in <20 ms after redispatch or contingency
Full N-1 / N-1-1 Screening
25 000-bus systems scanned in <6 seconds with Q-limit enforcement
Robust Reactive Limits
Automatic PV→PQ switching with hysteresis — no divergence
Instant PTDF & LODF
Sub-millisecond shift factors by reusing the factorized Jacobian
Designed for real-time security assessment, tight UC/ED coupling, voltage-collapse proximity monitoring,
and as the physics backbone for AI-driven grid control and digital-twin applications.
