摘要：In micro grid, the droop controlled micro power supply, the line impedance difference, the output voltage amplitude is not equal, and the microgrid complex structure and other factors will cause the reactive power of micro power output cannot achieve the same effect, so that reactive power circulation will appear between micro power supply. In order to solve this problem, an improved droop control strategy is proposed. That is to say, in traditional reactive droop control, line voltage drop and micro power access point voltage amplitude feedback are used as compensation amount for reactive droop control, which effectively tracks voltage change of microgrid and improves output voltage amplitude. The simulation model of microgrid is built in Matlab/Simulink. The simulation results show that the improved droop control can greatly improve the distribution precision of the reactive power sharing and improve the system stability of the microgrid.
