Aiming at the voltage and frequency instability caused by the primary control of the island mi-crogrid and the reactive power unevenness caused by the unbalanced circuit impedance, a quad-ratic control strategy based on the distributed multi-agent system is adopted. This paper is com-pleted to solve the voltage and frequency deviation due to droop control. The application of dis-tributed consistency algorithm under symmetric time delay is analyzed. The theoretical model is built in MATLAB/Simulink to verify the influence of delay on distributed consistency algorithm.
