The term micro grid is mentioned more and more in publications on distributed generation. It generally means a collection of consumers, generators and potential energy storage entities connected together and operated as a small grid which is connected to the main grid, but capable of operating a self-sufficient island. The micro grid is typically linked to the grid with the help of a switch, which allows it to work both in grid-connected as well as island mode. However, island operation is not currently permitted in the majority of countries.
