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.
With regard to the off-grid operation, the energy storage system has considerable importance in the microgrid. The ESS mainly provides frequency regulation, backup power and resilience features.
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.
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 .
The battery achieves significant revenue from the frequency regulation market. The breakdown of wholesale revenue is about 60% from frequency regulation, 39% from energy, and less than 1% from spinning reserve. The demand response revenue is reduced compared to the diesel-only microgrid because of the reduced EDGs.
