Mobilizing Grid Flexibility for Renewables Integration through Enhanced Computation

" summary

Research shows using topology control and flexible line rating as recourse in a two-stage stochastic unit commitment cuts dispatch cost substantially: simulations report ~15% savings with 3–4 line switches, a PJM case where switching a single line saves ~$100M over a high-load period, and a European test on 1,000-line data. Computation is heavy (48,000 binaries took >8 hours on a laptop) but a warm-start heuristic reduces solve time to under an hour.
