Two types of microgrids
The Microgrid Exchange Group defines a microgrid as "a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode." [pdf]
Typical Cases of Smart Microgrids
Microgrids are small-scale power grids that operate independently to generate electricity for a localized area, such as a university campus, hospital complex, military base or geographical region. . This section of the wiki features a compilation of microgrid case studies, showcasing some important applications for energy storage.
