An inverter connected to a grid and outfitted with anti-islanding protection is designed to disconnect the electrical supply from the grid if a blackout occurs. Anti-islanding protection is a way for the inverter to sense when the power grid is struggling or has failed. It then stops feeding power back to the grid.
Inverter-based DERs, such as PV and storage systems, feature built-in protection mechanisms that detect when they have become islanded from the distribution grid. Inverters have traditionally used a number of anti-islanding protection methods that have been classified as either passive or active.
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.
Northbrook, IL. Due to equipment and personnel safety dimensions, some jurisdictions apply additional methods to ensure that distributed energy resources (DERs) do not island. This appendix summarizes these concerns and supplementary anti-islanding protection strategies. Many methods can be used to protect against unintentional islands.
