概要	This paper presents a novel two-loop control system based on multi-input and multioutput equivalent-input-disturbance approach for inverter of distributed generation in gridconnected microgrid. The control system which consists of an inner loop and an outer loop ensures desired power flow from utility grid to sensitive local load and maintains voltage of the sensitive local load even when voltage sag/swell occurs in the utility grid. The inner loop of the control system is a voltage and current controller which is used to realize tracking control. The outer loop of the control system is a voltage sag/swell compensator which compensates voltage for the local sensitive load when voltage sag/swell occurs in the utility grid. The small gain theorem is used to guarantee the stability of the control system. Simulations are carried out in MATLAB/Simulink to verify the effectiveness of the control system.
