Distributed Optimal Power Flow Using ADMM
TLDR
A fully distributed and robust algorithm for OPF is proposed which does not require any form of central coordination and is based upon the alternating direction multiplier method (ADMM).Abstract:
Distributed optimal power flow (OPF) is a challenging non-linear, non-convex problem of central importance to the future power grid. Although many approaches are currently available in the literature, these require some form of central coordination to properly work. In this paper a fully distributed and robust algorithm for OPF is proposed which does not require any form of central coordination. The algorithm is based upon the alternating direction multiplier method (ADMM) in a form recently proposed by the author, which, in turn, builds upon the work of Schizas The approach is customized as a region-based optimization procedure, and it is tested in meaningful scenarios.read more

Distributed Energy Trading: The Multiple-Microgrid Case
TL;DR: In this article, a distributed convex optimization framework is developed for energy trading between islanded microgrids, where the problem consists of several island-grids that exchange energy flows by means of an arbitrary topology, and a subgradient-based cost minimization algorithm is proposed that converges to the optimal solution in a practical number of iterations.
