In recent years, energy storage technology is widely used in distribution networks. It can significantly improve stability and power quality of the grid. An improved droop control strategy for energy power storage converter is proposed here, which based on complex filter, dividing the voltage into positive and negative sequence components in the αβ ‐axis. This method has small amount of calculation and easy realisation. This strategy can improve the output power quality of energy power storage converter. Finally, it proved that the improved voltage control strategy can effectively shorten the time of voltage recovery in the case of the power fluctuation of the contact line, and provide reference for other access storage power distribution network operation control through MATLAB/Simulink simulation.
