Using virtual impedance to analyze the stability of LCL-filtered grid-connected inverters


This paper compares three current control methods for LCL-filtered grid-connected inverters, they are single-loop control based on inverter current feedback, that based on grid current feedback, and dual-loop control with capacitor current feedback active damping. The virtual impedance introduced by each method is identified, which comprises frequency… (More)
