As an island can only form when both conditions are true, they concluded that the "Probability of encountering an islanding is virtually zero"

In the event the grid fails, the local system must not feed the grid to prevent the possible creation of dangerous islanding.

The implication was that islanding was dangerous, and that some rules allowed cooperation to prosper while others didn't.

In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit.

Each black start unit must be able to demonstrate that it can startup another unit in close proximity to begin the islanding and synchronization of the grid.

This provides a very secure method of detecting islanding, because there are generally no other sources of THD that would match that of the inverter.

Ms. Williams, of Columbia, said she worried about "a sort of island - and I don't mean Martha's Vineyard - a sort of islanding of the conversation."

An example of such an approach, one that strengthens the case that islanding is largely a non-issue, is a major real-world islanding experiment that was carried out in the Netherlands in 1999.
