MG is an independent grid with both load and power generation.

MG is having option to be connected to the grid (via PCC - Point of Common Coupling ) or can be islanded.

MG is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid.

Intelligent monitoring and control of MG make it as a smart sub system for smart grid technology.

MG can include uncontrollable loads as well as distributed energy resources such as generators, storage devices, and controllable loads

MG is having a control strategy to maintain, on an instantaneous basis, real and reactive power balance when the system is islanded

MG over a longer time, to determine how to dispatch the resources.

The control system must also identify when and how to connect/disconnect from the grid.
