    Abstract: This paper proposed a converter simplified model which is suitable for fast simulation of large-scale energy storage systems based on the theorem of mean. Detailed converter model analysis and control algorithm are the basis of the simplified model. According to the electrical characteristic between the AC side and the DC side of the coupled convert, the study simplified the model. Moreover, this model elaborated the output characteristic through the controlled source, and it could simplify the topological structure of the converter.This paper removed the high-frequency components and intermediate processes, and the influence of the control algorithm on inverter characteristics is reserved in it to reduce the simulation calculation amount. It deduced an averaged-value model of the energy storage converter and obtained the iterative form of the model from the discretization of the averaged-value model. The results of the PSCAD/EMTDC experiment show that the proposed converter averaged-value model could improve the electromagnetic transient simulation speed of the large-scale energy storage system under the guarantee of simulation accuracy.
    Key words: averaged-value model; energy storage converter; PWM converter; fast simulation
