Operations and planning mitigation

Start with the failed or unsatisfactory optimization result and the constraint set that caused it.

Preferred action order

1. Fix data quality first: ramps, minimum output, up or down times, reserve requirements, network limits, and time-series assumptions.
2. Solve a simpler screening case before a larger one: DC before AC, dispatch before unit commitment, operations before expansion.
3. Add flexibility: storage, demand response, fast-start units, or revised reserve products.
4. Relieve congestion with topology, transmission expansion, or better siting.
5. Relax constraints or add slack variables only with explicit penalties and a clear explanation.

Working rules

• Do not call a system infeasible before checking data consistency.
• Separate economic congestion from physical AC infeasibility.
• Validate promising fixes in an AC tool when voltage or reactive limits matter.

Deliver

• The main binding constraints or infeasibility cause.
• The best near-term operational fix.
• The longer-term planning measure if the issue persists.
