Abstract

With the development of electrochemical energy storage technology and economic improvement of battery

battery energy storage power stations are rapidly applied in power systems. The battery energy storage system relies on the energy storage converter based on power electronics technology to realize grid connection

and its grid-connected dynamic characteristics are affected by the control algorithm of the energy storage converter. Based on the primary structure of a typical energy storage system

a dynamic frequency domain model of battery energy storage system is established in this paper. Through the self-stabilizing loop and the interaction loop in the model

combined with the frequency domain analysis method

the mechanism of the high-frequency oscillation of the system induced by the energy storage converter is studied. Simulation studies based on MATLAB/SIMULINK platform verify the correctness of theoretical analysis.
