About Short-circuit current of energy storage system
With the rapid development of the application of battery energy storage technology, its impact on the power grid is far-reaching. However, the research on the short-circuit current contributed by battery energy storage after AC short-circuit and its influence on power grid stability is still blank at home and abroad.

By using the proposed model, this paper characterizes the short-circuit behavior of two-stage BESSs under: 1) different operating modes, i.e. charging and discharging, 2) different type of FRT strategies, such as traditional CSC, and the recent DSC scheme compliant with the VDE-AR-N 4120 Technical Connection Rules [17], which requires injection .
utility-scale battery storage system with a typical storage capacity ranging from around a few megawatt-hours (MWh) to hundreds of MWh. Different battery storage technologies, such as lithium-ion (Li-ion), sodium sulphur and lead-acid batteries, can be used for grid applications. However, in recent years, most of the market.
The individual relays connected at the load branch can easily detect the fault due to very high short circuit current from grid. In IM, when there is a significant contribution from BESS, the AOC protection in relays R13 and R31 will detect the fault.
The paper summarizes the features of current and future grid energy storage battery, lists the advantages and disadvantages of different types of batteries, and points out that the performance and capacity of large-scale battery energy storage system depend on battery and power condition system (PCS).
