Microgrids also act as a tool to help users control and manage costs, thus sharing in the benefits of renewable energy and reducing carbon emissions.

In addition, they are designed not only for emergency power, but to operate in normal conditions providing important services to the main network and can be a valuable resource when the network is under stress, or need flexibility to balance resources.

Therefore, microgrids, in addition to security of supply to their users, provide other important benefits such as savings, robustness and the assured supply of quality and clean energy 24/365.

To form an island microgrid from renewable generation and have the capacity to supply quality energy 24 hours a day, every day of the year, a photovoltaic or wind generation plant, a Battery Energy Storage System (BESS) to balance generation with energy demand, inverters and software are needed.
