Microgrid Definitions
• U.S. DOE: A microgrid is a localized grouping of
electricity sources and loads that normally operates
connected to and synchronous with the traditional
centralized grid (macrogrid), but can disconnect and
function autonomously as physical and/or economic
conditions dictate.
• CIGRÉ Working Group: Microgrids are electricity
distribution systems containing loads and distributed
energy resources, (such as distributed generators,
storage devices, or controllable loads) that can be
operated in a controlled, coordinated way either while

connected to the main power network or while islanded.
