Renewable energies have introduced new challenges in the path to the smart grid with the starting point of traditional distribution systems. A proposal to overcome these challenges is to split distribution systems into many smaller ones, also called microgrids, which are easier to control and operate. However, the interaction and interconnection between these subsystems is a remaining challenge, where these groups of interacting microgrids are called networked microgrids. In this work, we present an energy management system to control and operate networked microgrids, that considers power flow equations for every subsystem, applies to every sort of topology, devolves individual control and operation to each microgrid controller to enhance privacy levels, and avoids the requirement of the distribution system as an interaction coordinator. We first introduce the problem statement using a traditional AC optimal power flow formulation, allowing the energy management system to work over meshed and radial configurations. Then the distributed optimization algorithm based on the alternating direction method of multipliers is presented and validated through some study cases to show its convergence and applicability.
