Abstract

In the isolated island microgrid, the parallel inverters generally use sag control to achieve power and voltage stability, but when the line impedance is not equal, each inverter cannot achieve equal reactive power. In this paper, virtual impedance is added to the traditional sag control to achieve the equal division of reactive power. Finally, through Matlab simulation comparison, it is verified that the sag control with virtual impedance can achieve equal reactive power.
