AC Power-Flow & N-1 Screening
for the Eastern Interconnect.
Power systems studies that took overnight runs on legacy desktop tools now complete in minutes. PowerOps is a Python-first engine for AC/DC power-flow, N-1 screening, TrLim, and MIC deliverability on the full Eastern Interconnect — 93,447 buses, standard structured outputs.

13/13 contingency gate PASS
screened in ~15 min
ERCOT 2,220-contingency case
A Full Study Pipeline in One Tool
PowerOps replaces a stack of separate tools with a single Python engine that reads industry-standard RAW network files and produces structured study reports.
AC Power Flow
Full Newton-Raphson solver with FDNS (Fast-Decoupled) acceleration. Tap control, PV→PQ flip, remote regulation, and N-1 auto-fallback. Validated against reference power-flow solvers at transmission scale.
N-1 Contingency Screening
Branch violation detection across the full contingency list. BranchViol, VoltViol, and CaseSum reports in structured CSV format.
Transfer Limit (TrLim)
Proportional transfer limit study using DC sensitivity (DFAX). Validated against reference solvers on ERCOT 901→904 transfer path.
ATC / AFC
Available Transfer Capability end-to-end: TTC − TRM − CBM − ETC. Full pipeline — source area, sink area, and posted path in one command.
MIC Deliverability
Batch maximum-deliverable capacity screening for interconnection queues. DC (SCED) + AC verify mode. Full EI in under 50 seconds via HTTP API.
N-1 Overload Map
Geographic visualization of worst-case contingency loading. Per-contingency drill-down panel, kV filter, and real bus locations on the Eastern Interconnect topology.
From RAW File to Report
PowerOps plugs into the network model files you already have. No model conversion, no new network build.
Load Your Model
Point PowerOps at any v29–v36 RAW network file. Bus, branch, load, generation — parsed automatically with full floating-point fidelity.
