Contingency Mitigation

Start with a solved base case and a ranked list of critical contingencies.

Preferred action order

1. Verify the contingency definitions, monitored elements, and limits.
2. Group critical contingencies by common corridor, interface, or weak area.
3. Apply preventive actions first: redispatch, shunts, tap changes, or topology changes that help multiple contingencies.
4. Evaluate corrective actions next: post-contingency switching, redispatch, or RAS schemes with explicit triggers.
5. Use load shedding only as a last-resort action and state that clearly.
6. For recurring problems, recommend reinforcement or a revised operating guide.

Working rules

• Do not trust contingency results from a bad base case.
• Prefer actions that improve a family of contingencies rather than a single outage.
• Re-run the full monitored set after any candidate fix.

Deliver

• The critical contingencies and the shared weak pattern.
