Microgrids aren’t a new idea. In industry parlance, a microgrid is a small network of electricity users with access to a local source of energy. The users are all directly connected to the central grid, but during outages, the entire small network can disconnect itself from the central grid, or operate in “island mode,” to.

This description includes three requirements: 1) that it is possible to identify the part of the distribution system comprising a microgrid as distinct from the rest of the system; 2)
"A microgrid is a collection of interconnected loads and dispersed sources of energy that operates as a unified, performance contributes to the grid and is contained within well delineated
Microgrids können unabhängig vom Stromnetz agieren und erhöhen die Versorgungssicherheit bei Netzstörungen. Im Gegensatz zu Smart Grids, die smarte Technologien integrieren, sind Microgrids autark betreibbar. Sie
The technologies that support smart grids can also be used to drive efficiency in microgrids. A smart microgrid utilizes sensors, automation and control systems for optimization of energy production, storage and distribution. Smart microgrids
A smart microgrid utilizes sensors, automation and control systems for optimization of energy production, storage and distribution. Smart microgrids are designed to be resilient and reliable, able to quickly respond to changes in demand or supply disruptions.
It can be connected to utility grid (grid mode) or operated independently when isolated from utility grid (island mode) during faults or other external disturbances, thus increasing the quality of supply, customers can obtain a higher efficiency, cheaper and cleaner energy. This ability of microgrids is one of the key features.
The performance of microgrid operation requires hierarchical control and estimation schemes that coordinate and monitor the system dynamics within the expected manipulated and control variables.
The benefits of microgrids, detailed in Fig. 1, show that the autonomous operation of such systems is eventual. Therefore, microgrids viably enable an intelligent grid environment of an electric network. The integration of various autonomous systems in one encompassment requires robust and resilient control, monitoring and protection techniques.
But because microgrids are self-contained, they may operate in “island mode,” meaning they function autonomously and deliver power on their own. They usually are comprised of several types of distributed energy resources (DERs), such as solar panels, wind turbines, fuel cells and energy storage systems.
The control system of a microgrid must continuously analyze and prioritize loads to maintain a balance between power generation and consumption. Microgrid loads are usually critical or non-critical 6. Critical loads in hospitals, nursing homes, and data centers are essential to running a facility and must never be interrupted.
