With the spread of distributed power generation and the popularization of electric vehicles, power storage technology will be further developed on the demand side. Focusing on the benefit analysis and economic operation of user side energy storage, the status of its research in terms of life loss cost modelling,multiple revenue stream profit models, and joint optimization of multiple application scenarios is sorted out, and typical cases of actual operation at home and abroad are introduced. Finally, the development prospects of user side energy storage are summarized in terms of technology, policy and market, and possible future research directions are foreseen. It is hoped that the work can provide useful references for relevant research and industrial development in domestic user-side energy storage.
