A microgrid is a self-sustained system, consisting of interconnected distributed energy resources and loads under a common control scheme that can operate in an independent mode during grid failures. Energy resources may be renewables like solar and wind, diesel generators, gas turbines, battery storage, electric vehicles and/or demand/response. Microgrids may serve applications ranging from industrial and commercial, campus/institutional, communities to military installations, in an autonomous or grid-connected manner.
Autonomous: Off-grid systems where generated power is consumed to meet the needs of the local demand. Partly autonomous systems are also covered.
Grid Connected: Generate and distribute power within the local grid and import/export power from a utility source
It consists of the central and peripheral Microgrid controllers, data loggers, required communication equipment, and measuring instruments as well as a SCADA/EMS server for proper system management.
