| description | The invention provides a reactive power sharing control method and control device of a distributed microgrid. The control method comprises the steps of calculating a relation expression between a reactive power Qi of a micro power supply and circuit impedance Xi of the micro power supply in the distributed microgrid; and calculating reactive power relative deviation Delta Q between reactive powers Qi and Qj of two arbitrary micro power supplies in the distributed microgrid, and enabling the reactive power relative deviation Delta Q to be within a preset range by adding adaptive virtual impedance into each micro power supply and adjusting an adaptive coefficient K. By introducing the adaptive virtual impedance into each micro power supply of the distributed power grid, the reactive power relative deviation of two arbitrary power supplies in the distributed power grid is maintained within the preset range, and the reactive power allocation accuracy can be improved.
