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.
In the CES model, energy storage resources are put into a sharing pool, which can be called an “energy storage cloud”. Under this situation, energy storage resources and energy storage services will present “cloud” features to users, which include aggregation, collaboration, virtualization, and so on.
The physical transmission party controls the charging and discharging to realize the electric energy delivery. Finally, the platform settles the revenue of each party according to the traded electricity. The goal is to minimize the total system cost during the operation and dispatch of the cloud energy storage service provider.
The system architecture and operation mode of cloud energy storage proposed based on the characteristics of user-side distributed energy storage have laid the foundation for the commercialization of cloud energy storage.
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.
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.
