Computational Analysis of Sparsity-Exploiting Moment Relaxations of the OPF Problem
Daniel K. Molzahn, Cedric Josz, Ian A. Hiskens +1
With the potential to find global solutions, significant research interest has focused on convex relaxations of the non-convex OPF problem. Recently, "moment-based" relaxations fro…
