Operational characteristics of cloud energy storage

What is cloud energy storage?

Cloud energy storage (CES) in the power systems is a novel idea for the consumers to get rid of the expensive distributed energy storages (DESs) and to move to using a cloud service centre as a virtual capacity.

What are the SOC constraints of cloud storage energy?

The SOC constraints of the cloud storage energy mean that the storage energy cannot be overcharged or discharged during operation, indicates the change in external characteristics of ES in year y, and Cycles indicates the number of optimisation cycles within the warranty period.

Can cloud energy storage reduce operating costs?

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.

What is the relationship between the participating subjects of cloud energy storage?

The relationship between the participating subjects of the cloud energy storage service is centered on the cloud energy storage service provider. Distribution networks and user-side small energy storage devices are the target customer groups of the service business.

What happens when Ces users charge their cloud storage?

When a CES user charges its cloud storage, the energy storage facility charges by absorbing energy from the grid. When CES users discharges their cloud storage for their own use, the energy storage facility releases the energy to the grid to compensate for the corresponding load of the CES users.

What are the differences between user-side small energy storage and cloud energy storage?

The specific diferences are as follows: User-side small energy storage participates in the optimization and scheduling of the cloud energy stor-age service platform, which can aggregate dispersed energy storage devices.
