The control mode of interlinking converter directly affects the stable operation of AC/DC microgrid. The control method based on droop theory of AC/DC interlinking converter under isolated network operation is analyzed, including bidirectional droop control, unitized control of droop characteristics, and unitized hybrid droop control. For power flow direction determination and power reference value selection of insufficiency, a control strategy based on integrated droop coefficient is proposed. The process of calculating the integrated droop coefficient is discussed in detail. The droop coefficient ratio of AC/DC hybrid microgrid system is defined. The hybrid microgrid power surplus and deficiency value are compared. The small value acts as a power reference for the interconnected converter, minimizing the impact of a single subnet on the contact subnet from deviating the rated operating conditions. Finally, the simulation model of AC/DC hybrid microgrid is built by using MATLAB/Simulink simulation software to verify the feasibility and effectiveness.
