Network Contingency Analysis Results

This dataset provides detailed results from power grid contingency analysis, covering N-1 and N-2 scenarios, post-contingency flows, voltage and thermal violations, and recommended corrective actions. It enables planners and engineers to assess grid reliability, identify vulnerabilities, and evaluate mitigation strategies for operational and planning purposes.

Behind this dataset

Same schema. As many rows as you need.

These 105 rows came out of a blueprint — 17 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with

Contingency ID unique per scenario
Contingency type: single element (N-1), double element (N-2), common mode
Outaged element: line, transformer, generator
Post-contingency power flows
Voltage violations: buses outside limits (typically ±5%)
Thermal overloads: elements above emergency rating
Convergence status of power flow solution
Severity index or ranking
