This paper proposes a new anti-islanding method for single-phase grid-connected photovoltaic (PV) systems using Goertzel
algorithm. The proposed scheme is based on inducing increases or decreases of frequencies of load voltage and current that is in
the form of existences or periodical variations of the reactive power components. The frequency detection is needed to apply this
power variation method to the grid-connected power converter. The proposed method is able to get a fast detection for anti-
islanding without the effect of harmonics and noises. The simulation and experiment results validate the effectiveness of the
proposed method.
