Seminar with Prof Miguel Anjos

Professor Miguel Anjos from the University of Edinburgh is giving a seminar on: Tight-and-Cheap Conic Relaxations for AC Optimal Power Flow and Optimal Reactive Power Dispatch

Abstract: The classical alternating current optimal power flow problem is nonconvex and generally hard to solve. We propose a new conic relaxation obtained by combining semidefinite optimization with RLT. The proposed relaxation is stronger than the second-order cone relaxation, competitive with the recently proposed QC relaxation, and up to one order of magnitude faster than for the semidefinite chordal approach on benchmarks with up to 6515 nodes, with comparable global bounds. We extend the approach to optimal reactive power dispatch, which requires the introduction of binary and integer variables, and obtain with similar results and performance.
