Microgrids provide added resilience features to traditional centralized power grid designs and may be able to provide flexibility for different geographies such as islands with unique features. [pdf]
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.’’ Off-grid microgrids are constructed where there is a significant need for electricity but no access to a wide-area electrical grid..
