With the acceleration of the construction of new power systems

lithium-ion battery(LIB)energy storage plays a key role in the transformation of power systems due to its high energy density and fast response characteristics.This paper reviews and discusses the technical challenges and development planning issues associated with large-scale lithium-ion battery energy storage applications in new power systems. Firstly

the research and development status of modeling

state estimation

and safety assessment of lithium-ion battery energy storage ontology equipment in complex environments are reviewed. Secondly

the application of lithium-ion battery energy storage is reviewed from the three-level architecture of microgrid

distribution networks and transmission networks. The development status of LIB energy storage grid-connected control technologies and the distinct requirements of diverse microgrid scenarios

such as industrial parks and ships

are analyzed.Additionally

the coordination mechanism of vehicle to grid(V2G)technology and mobile energy storage vehicle in flexible regulation of distribution network

the support strategies for lithium-ion battery energy storage under[N-0/N-1]dual states of large power grids and the multi-market coupling trading modes for battery energy storage are discussed.Finally

the prospects for the large-scale application of lithium-ion battery energy storage in new power system is put forward.This study can provide a practical reference for constructing of lithium-ion battery energy storage technology systems that meet the evolving needs of new power systems.
