The paper builds a unified equivalent modelling simulation system for electrochemical cells. In this paper, the short-circuit fault of DC bus in energy storage power station is analyzed and simulated. The short circuit of DC bus is composed of three parts: short circuit current provided by energy storage battery, short circuit current provided by power grid and short circuit current provided by DC energy storage capacitor. The factors that affect the amplitude of three kinds of short-circuit current are summarized to provide reference for reducing the DC short-circuit current of energy storage station.
