As an important two-way resource for efficient consumption of green electricity, energy storage system (ESS) can effectively promote the establishment of a clean, low-carbon, safe and efficient new energy system. In order to assist the decision-making of ESS projects and promote the further development of the ESS industry, this paper proposes a user-side ESS optimal
However, In 2021, the installed capacity of distributed PV systems exceeded 10GW [20], while the cumulative installed capacity of user-side energy storage reached approximately 1.17GW [21]. However, compared to China''s industrial electricity consumption, there is still considerable scope for improvement.

With the new round of power system reform, energy storage, as a part of power system frequency regulation and peaking, is an indispensable part of the reform. Among them, user-side small energy storage devices have the advantages of small size, flexible use and convenient application, but present decentralized characteristics in space.
Operational mechanism of user-side energy storage in cloud energy storage mode: the operational mechanism of user-side energy storage in cloud energy storage mode determines how to optimize the management, storage, and release of energy storage resources to reduce user costs, enhance sustainability, and maintain grid stability.
The specific differences are as follows: User-side small energy storage participates in the optimization and scheduling of the cloud energy storage service platform, which can aggregate dispersed energy storage devices.
Therefore, the optimal allocation of small energy storage resources and the reduction of operating costs are urgent problems to be solved. In this study, the author introduced the concept of cloud energy storage and proposed a system architecture and operational model based on the deployment characteristics of user-side energy storage devices.
In the future, the cloud energy storage platform has broad applications in optimizing the dispatch of small devices on the user side. The existing research on cloud energy storage mainly focuses on resource planning and scheduling and economic optimal allocation, and there are few researches on user-side distributed energy storage.
User-side small energy storage devices as well as the power grid need to be submitted to the platform before the day supply/demand power information. The platform side needs to sort out the total supply of power and total demand power information for each time period and release the information.
