Reliability Analysis Algorithm for Multiple Microgrids in Distribution Systems Based on Complex Network Mathematical Theory

Abstract

It exists a great potential in microgrids connected to distribution systems of being taken into advantage reconfiguration possibilities with the purpose of achieving the quality of service regulatory requirements that become more demanding each day. In addition, it is possible to optimize the network operators’ income by increasing the incentives for upgrading the quality indexes. In this paper, it's proposed an evaluation algorithm of the connection points of multiple microgrids in a distribution system that upgrades the reliability of the system as a whole, being based in complex network analysis (CNA), a perspective of power systems that allows the evaluation of an electrical system as a graph. For that, a model of a trial system is made from the CNA point of view utilizing the MATLAB software and afterwards, as validation of the proposal of this work, the system's reliability is evaluated by connecting multiple microgrids into critical nodes provided by the CNA making use of the NEPLAN tool of power systems simulation.
