A reference current perturbation method for islanding detection of a multi-inverter system

An active islanding detection method without destabilizing the system gives the advantage of accurate decision and the capability to keep the micro-grid energized while islanding occurs. Harmonic and perturbation current injection are such active methods, but none in the literature has discussed about islanding detection in multi-inverter systems. This paper proposes an active islanding detection method for multi-inverter systems which works …
