Islanding detection technique based on vector shift / Nurul Nadia Omar

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical power from the electric utility is no longer present. Islanding can be hazardous to the DG, and should be prohibited. Thus, a reliable and fast detection technique is needed t...
