To reduce reactive power sharing error caused by mismatched feeder impedance in an islanded microgrid(MG) with multiple distributed generation units(DGs)
this paper proposes an event-triggered voltage distributed cooperative control(VDCC). It aims to improve the accuracy of reactive power sharing by the stable voltage synchronization between DGs. Firstly
an event-triggered voltage consensus control was used to save communication resources by reducing the transmission of sampling voltage. Then
a voltage H∞ tracking control with communication input-delay was designed in the voltage inner-loop of inverter
and its stability criterion was derived by using the Lyapunov functional method. Finally
the effectiveness of the proposed method was proved by a MG simulation model in MATLAB/Simulink.
