Energy storage power station plays an important role in solving the problem of intermittency of renewable energy and improving the stable operation of power system. In this paper

the research progress of energy storage power station both at home and abroad is comprehensively reviewed from the aspects of research status

composition structure and control strategy

respectively. Firstly

the research status of the energy storage station is introduced

more than two thousand Chinese and English documents between 2012 and 2022 are screened based on CNKI and WOS databases. The similarity and heterogeneity of domestic and foreign scholars in the research field of energy storage power station are compared by keyword co-occurrence mapping and timeline mapping using CiteSpace visual mapping analysis. Then

the basic structure of the energy storage power station is introduced

with the existing research status on battery pack

energy storage converter and energy management system in particular. Finally

the control strategy of the energy storage power station is introduced and

based on the auxiliary grid service of the energy storage power station

the research in the aspects of automatic generation control

primary frequency regulation

and peak regulation is summarized.
