Local solutions of optimal power flow problem

Coauthors: Andreas Grothey, Ken Mckinnon, Paul Trodden


Optimal power flow (OPF) is a well studied optimization problem in electricity industry. Over the last two decades it has become a standard tool for planning, real time operations and market auctions.
OPF is nonlinear optimization problem and the existence of locally optimal solutions has been a question of interest for decades. Often it is conjectured that OPF feasible region is convex. In this talk, we present examples of local solutions of OPF on a range of power systems networks. We also show that a recent reformulation of OPF as SDP problem
sometimes fails to recover feasible solutions of OPF.
