This paper reviews distributed/decentralized algorithms to solve the optimal power flow
(OPF) problem in electric power systems. Six decomposition coordination algorithms are …

The term smart grid refers to a modernization of the electrical network consisting in the
integration of various technologies such as dispersed generation, dispatchable loads …

We propose a branch flow model for the analysis and optimization of mesh as well as radial
networks. The model leads to a new approach to solving optimal power flow (OPF) that …

For nearly 20 years, the Test Feeder Working Group of the Distribution System Analysis
Subcommittee has been develo** openly available distribution test feeders for use by …

This tutorial summarizes recent advances in the convex relaxation of the optimal power flow
(OPF) problem, focusing on structural properties rather than algorithms. Part I presents two …

The power flow equations relate the power injections and voltages in an electric power
system and are therefore key to many power system optimization and control problems …

The optimal power flow (OPF) problem is nonconvex and generally hard to solve. In this
paper, we propose a semidefinite programming (SDP) optimization, which is the dual of an …

This tutorial summarizes recent advances in the convex relaxation of the optimal power flow
(OPF) problem, focusing on structural properties rather than algorithms. Part I presents two …

Over the past half-century, Optimal Power Flow (OPF) has become one of the most important
and widely studied nonlinear optimization problems. In general, OPF seeks to optimize the …

The optimal power flow (OPF) problem determines a network operating point that minimizes
a certain objective such as generation cost or power loss. It is nonconvex. We prove that a …
