The present paper aims to provide a tool for the analysis of Smart Micro Grids at the level of energy policies and management of power fluxes. The tool is presented as a simulator developed in Matlab that allows implementing a wide variety of management algorithms taking into account a wide range of variables. The level of flexibility is high, being able to integrate different levels in the algorithm to control isolated SMG, SMG interconnected between them, or hybridization of them. This is possible using the models of the most representative elements of these systems such as a photovoltaic field, batteries, generators, loads... Amodule for capturing parameters of the different elements of the SMG. Spreadsheets with external data for each SMG to simulate and finally with a script that allows to carry out the simulation of the length and timing chosen by the user. It illustrates the correct operation of the simulator with the implementation of some energy management algorithms. In this study case, it is also intended to demonstrate the maneuverability of the simulator, allowing the implementation of two different algorithms to study how they affect the same house and comparing the results. The program is expandable to add other interesting elements such as wind generators, movable loads... And it could also be expanded to carry out the reactive energy study. It is not considered interesting to increase the complexity of the models, as this would become in a much higher simulation times.
