摘要：

This paper proposes an alternative control method to interconnect DG interfacing converter to grid-tied and islanding microgrids, without using any AC voltage sensor. By properly using the flexible control of virtual harmonic impedance and droop control, the line current quality and power control accuracy in grid-tied mode are improved. In addition, the supply voltage quality problem in islanding mode can be solved in a similar manner, with slight modification of the virtual impedance. Verification results are provided to prove the correctness of the proposed method.
