[leocuisine]

Existing-term check

I searched _wiki/ and database/json/ for reserve secure constraints and did not find an exact match.

Proposed term

• Title: Reserve secure constraints
• Proposed term ID: reserve-secure-constraints

Source / context

• Paper title: "Secured Reserve Scheduling of Pumped-Storage Hydropower Plants in ISO Day-Ahead Market"
• DOI / canonical version: https://doi.org/10.1109/TPWRS.2021.3077588
• Institutional copy with abstract: https://scholarsmine.mst.edu/ele_comeng_facwork/4424/

Notes

• The paper explicitly introduces the phrase "reserve secure constraints," so this should likely be a term page rather than a generic reserve page subsection.
