A microgrid (MG) is a local entity that consists of distributed energy resources (DERs) to achieve local power reliability and sustainable energy utilization.
In the optimal system configuration scheme, the electric energy in the microgrid is mainly supplied by wind energy and solar energy jointly, but in other combination schemes, the electric energy is only supplied by wind energy or solar energy alone. A microgrid system where energy sources are mixed for power supply has more economic advantages than a single

This paper provides a critical review of the existing energy storage technologies, focusing mainly on mature technologies. Their feasibility for microgrids is investigated in terms of cost, technical benefits, cycle life, ease of deployment, energy and power density, cycle life, and operational constraints.
Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .
Concerning the storage needs of microgrids, electrochemical technologies seem more adapted to this kind of application. They are competitive and available in the market, as well as having an acceptable degree of cost-effectiveness, good power, and energy densities, and maturity. The modularity of electrochemical technologies is another advantage.
As discussed in the earlier sections, some features are preferred when deploying energy storage systems in microgrids. These include energy density, power density, lifespan, safety, commercial availability, and financial/ technical feasibility. Lead-acid batteries have lower energy and power densities than other electrochemical devices.
