What is islanding in a single-phase grid connected inverter?

In some cases, islanding is intentional. When this occurs, the inverter detects the grid event and automatically disconnects itself from the grid, creating an island intentionally. The single-phase grid connected inverter is then forced to push power to the local circuit. This method is used as a backup power generation system.

Can a grid-connected inverter detect islanding?
