Island scheme minimizes grid outages

Many renewable energy sources can be placed close to energy consumers, which eases the burden on the main lines of the electrical grid and reduces losses from long-distance transmission. Tying many small distributed power generation systems into the grid could also be the key to limiting the damage from outages.

A strategy for deliberately breaking the grid into self-sufficient islands in the event of a major failure relies on distributed power sources. The system automatically reconfigures the grid into islands based on how much energy is being produced and used at the local level.
