A Distributed-Controlled Harmonic Virtual Impedance Loop for AC Microgrids [PDF]
IEEE Transactions on Industrial Electronics, 2021 Proportional harmonic current sharing among inverters is desired in ac microgrid with nonlinear loads. Usually, virtual impedance is emulated to achieve good harmonic current sharing at the cost of increased harmonic voltage distortion in the system.
