Grid integration constraints are limiting the deployment potential of renewable energy sources (RESs). Therefore, while RESs are essential components to reach the key objectives, energy storage is the enabler that facilitates the integration of RESs in a cost-effective and flexible manner.
No matter what the type of microgrid, energy storage is important to the success of the system. To store energy for future use, a microgrid owner needs an energy storage system. Should a cloud block the sun or the wind subsides, a microgrid can use its stored energy to keep the power on.
The difference between a grid-connected system and a microgrid lies in how it operates, and particularly its level of independence from the main electrical grid. The primary distinctions: 1. Dependence on the main grid: Grid-connected systems still rely on the main grid as their primary source of power.
This paper provides a critical review of the existing energy storage technologies, focusing mainly on mature technologies.

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 .
2. One-way power flow: Grid-connected systems typically have a one-way power flow, where electricity flows from the grid to the system for consumption. These systems do not typically have the capability to export excess energy back to the grid. 3. No energy storage: Grid-connected systems typically do not include energy storage systems.
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.
