Abstract
The droop-controlled inverter can be modeled as a controllable voltage source with output impedance in series. However, dynamic performance in islanded microgrid mode is highly sensitive to the inverter output impedance. In this paper, a three-phase voltage source inverter (VSI) control method based on linear active disturbance rejection control (LADRC) is proposed to decouple the output impedance of the three-phase inverter in dq frame to simplify the output impedance model. Moreover, LADRC can significantly reduce the amplitude-frequency response of the output impedance. Compared with the conventional PI double-loop control method, LADRC can dramatically improve the dynamic performance during load switching.
