MWClear runs a connected N−1 thermal screen on your PSS/E RAW v33 or MATPOWER model. Where the imported data supports the selected scope, it reports normal-operation and N−1 headroom, the binding branch, initiating outage, and modeled rating delta.
Runs locally. No model upload. No telemetry.

Decision output
The decision layer
Built for project developers, consultants, and network teams deciding which sites justify a full connection study.
Normal-operation and connected N−1 thermal headroom, reported separately in MW.
The monitored line or transformer, the initiating outage, and the modeled margin.
The binding branch’s modeled rating delta and the candidate curtailment required under the binding outage.
A capacity map and alternative buses calculated from the same model and assumptions.
Validation evidence · v0.6.0
The MWClear engine is cross-checked against an independent pandapower calculation path for flows, headroom, binding constraints, and outage classes.
The independent path uses pandapower’s DC matrices. Selected preventive-dispatch cases are also solved with CVXPY/CLARABEL. Qualifying cut-set findings can be replayed by a separate verifier using exact rational arithmetic. SHA-256 manifest ↗
From model to answer
Use MWClear to choose which connection points and scenarios deserve deeper engineering. It does not replace the grid operator’s study.
Use your existing PSS/E RAW v33 or MATPOWER network model. It stays on your machine.
Choose the bus, MW, load or generation direction, ratings, and the contingency scope.
Receive a decision page, full local evidence, input hash, and repeatable analysis ID.
Scope and confidence
Calculated results, targeted AC checks, and exact certificates are labeled separately. Unsupported components return a partial-model result; MWClear does not issue a connection decision for unsupported scope.
Thermal limits, generator capability, intact and connected single-branch outages.
Targeted AC spot checks and exact-rational cut-set certificates replayable by a separate verifier.
A replacement for protection, stability, harmonics, or the grid operator’s full study.
