Islanding Detection Using a Micro-Synchrophasor for Distribution Systems with Distributed Generation

Energies, 2020
Distributed Generation (DG) has changed the power generation system to small-scale instead of large-scale generation. The demanding issue with the interconnection of DG is the detection of unintended islanding in a network.
