This paper proposes a highly adaptable cloud energy storage (CES) model, which aggregates underutilized energy storage resources in the region and trades the resources together with
The development of energy storage technologies is still in its early stages, and a series of policies have been formulated in China and abroad to support energy storage development. Compared
Flywheel energy storage system (FESS) is one of the most satisfactory energy storage which has lots of advantages such as high efficiency, long lifetime, scalability, high power density, fast
Energy storage technologies are playing an increasingly significant role in helping the Asia-Pacific region meet clean growth targets. The technologies enable energy that is produced at one time to be used at a later time, facilitating more
With the increase of the installed capacity of electrochemical batteries, how to maximize the benefit of large-scale energy storage system(ESS) has become an urgent problem. Therefore,
where W is the total energy storage density, W rec is the recoverable energy storage density, and η is the energy storage efficiency. P max represents the maximum polarization, P r is the
Energy storage continues to go from strength to strength as a sector, with the buildout in leading markets like UK and California/Texas accelerating and other states and countries close behind. In it, you can read
The results show that the energy storage optimization proposed in this paper can ensure the interests of the power supply side, the user side, and the power sales company, and is more
(3) Economic benefits of user-side energy storage in cloud energy storage mode: the economic operation of user-side energy storage in cloud energy storage mode can reduce operational costs, improve energy storage eficiency, and achieve a win–win situation for sustainable energy development and user economic benefits.

Thirdly, research on the user-side is mainly limited to residential area users, while there is limited research on users who can configure energy storage devices themselves, such as industrial users, without considering the initiative of such users to participate in energy storage pricing.
However, the disorderly management mode of user-side energy storage not only causes a waste of resources, but also brings hidden dangers to the safe operation of the power grid, such as stability, scheduling and operation, power quality and other problems.
The user-side distributed energy storage will keep part of the stored power for self-use. At the same time, they will sell the remaining idle power to energy storage operators through the cloud energy storage service platform to earn additional revenue.
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. Therefore, the optimal allocation of small energy storage resources and the reduction of operating costs are urgent problems to be solved.
