"Webbconvex barrier can be a severe limitation on the effectiveness of relaxed veriﬁers based upon it. While the convex relaxation barrier can be bypassed in various ways (e.g. considering relaxations for multiple neurons [34]), as noted in [32, Appendix A] all existing approaches that achieve this do so by trading off clarity and speed.

Exact Convex Relaxation of Optimal Power Flow in Tree Networks

Webb1 juni 2024 · Optimal power flow (OPF) problems are ubiquitous for daily power grid operations and planning. These optimal control problems are nonlinear, non-convex, and computationally demanding for large power networks especially for OPF problems defined over a large number of time periods, which are commonly intertemporally coupled due to … Webb18 maj 2016 · Abstract. This paper proposes three strong second order cone programming (SOCP) relaxations for the AC optimal power flow (OPF) problem. These three relaxations are incomparable to each other and two of them are incomparable to the standard SDP relaxation of OPF. Extensive computational experiments show that these relaxations …
