Influence Analysis of Virtual Impedance on the Stability of Parallel System of Inverters with Different Voltage Levels

Using virtual impedance technology to optimize the double closed-loop control structure can improve the equivalent output impedance of the inverter to be inductive and enhance the accuracy of power distribution by traditional inductive droop control strategies in low-voltage micro-grids, thus inhibi...
