© 2017 IEEE. In virtual flux droop method, power sharing is achieved by adjusting flux amplitude and angle which has some advantages of simplicity of control and lower voltage and frequency deviation. In this paper, a switch module of power calculation was firstly designed to balance system dynamic response and power fluctuation in flux droop controller. Then an improved direct flux controller was proposed to reduce the flux pulsation by tighter flux linkage control. At last, simulation results prove that the improved virtual flux droop method has better dynamic and static performance.
