The battery energy storage power station has the advantages of short construction period

fast response speed and diverse application modes. It can be applied to the grid side to realize various functions such as emergency control

peak shaving

frequency modulation and voltage regulation. This paper summarizes the development status of domestic power grid side energy storage power station from three aspects of situation policy

engineering application and technology development

and expounds the characteristics and structure of typical case in Hunan power grid—Langli Energy Storage Power Station. Based on this

the paper focuses on the analysis of the engineering realization process and operation strategy of energy storage power station. Finally

combined with the ubiquitous power internet of things construction

the key technical issues faced by the regulation and operation of the energy storage power station are put forward.
