Abstract: The importance of energy management technology for energy storage power plants in improving the operating efficiency of energy storage power plants and reducing the cost of the whole life cycle is increasing day by day. This paper first expounds the relevant policies, standards and development status of the 100-megawatt electrochemical energy storage power station. Secondly, the data processing technology and communication technology architecture and application status of electrochemical energy storage power station are analyzed in detail. Thirdly, this paper summarizes the external demands and dispatching management technology of energy storage power station, and clarifies the energy management and control technology in each battery cluster level and module level in the energy storage system. Finally, the prospects in the future work of energy management technology for 100-megawatt electrochemical energy storage power station are put forward.
