In this paper, a novel intermittent reactive-power-variation (RPV) method based on loads’ resonance frequency detection is proposed to reduce the injected reactive power. The RPV method detects the frequency of point of common coupling (PCC) and outputs the minimum reactive variation, which perturbs the frequency of PCC to the frequency thresholds decided by the utility standards when the islanding...
In this paper, a novel reactive-power-variation (RPV) method of distributed generation (DG) inverter is presented. The proposed RPV method detects PCC frequency and outputs the minimum reactive variation which can just deviate the frequency of PCC to the frequency thresholds decided by the utility standards when the islanding condition happens. Compared with the traditional bilateral RPV method, the...
