This paper studies various energy storage technologies and their applications in microgrids addressing the challenges facing the microgrids implementation.
Since most microgrid generating sources lack the inertia used by large synchronous generators, a buffer is needed to mitigate the impact of imbalances of electricity generation and demand. Microgrids also lack the load diversity of larger geographical regions, so they must deal with much greater relative variability.

While storage value has been identified in many cases, three use cases are essential when it comes to off-grid systems: power quality, power reliability, and balancing support. Indeed, energy storage can enable time shifting at the time of excess low cost generation and the release of energy in times of peak demand [7 ].
Energy sources that comprise the microgrid include technologies such as diesel generators, fuel cells, PV panels, and wind turbines associated with storage resources. Energy storage technologies play a key role in the operation of the system.
