Benefit Assessment Analysis of Electrochemical Energy Storage

Along with the power fluctuation and other problems caused by large-scale grid connection of renewable energy, electrochemical energy storage has been widely concerned by researchers. Firstly, the technical characteristics and application scenarios of important electrochemical energy storage are summarized in this paper. Then the analysis focus on the evaluation indexes of the economic and social benefits of electrochemical energy storage on the generation side, grid side and user side. Finally, in order to adapt to the landing of carbon peaking and carbon neutral targets, and combined with the implementation of time-sharing tariffs, energy storage planning problems that need further in-depth research are proposed in view of the shortcomings in existing energy storage planning studies, which are of great significance for improving the adaptability of subsequent energy storage planning studies.
