Abstract Multiple inverters are connected to the distribution network with complex non‐linear loads and may interact background harmonics in some cases. In addition parallel resonance caused by harmonic current, voltage also causes series resonance. The matching of frequencies current results serious distortion grid‐connected bus waveform, or even threatens stability its operating point. A gene...

In this article, a method is proposed to increase the accuracy of reactive power-sharing for parallel-connected inverters in Microgrid, done by automatically adjusting values virtual impedance output voltage inverters. The impedances are adjusted compensate difference due influence line impedances. will be adaptively according change load, greatly improves power sharing correct ensure stability...
