摘要：
The use of the virtual admittance concept for harmonic and/or unbalance compensation in microgrids when multiple inverters operate in parallel is proposed in this paper. The virtual impedance concept has been traditionally used for these purposes. However, one drawback of the virtual impedance is that it can only be applied to distributed generation (DG) units operating in voltage control mode (VSI-VCM), but is not applicable to DG units working in current control mode (e.g., current-regulated voltage-source inverters, VSI-CCM). Contrary to this, the proposed method can be used in any converter topology and control mode, including VSI-CCM and VSI-VCM.
