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.
The electrical energy supplied by the energy storage device is shown in Table 2. This time, the distribution network's power demand is 675 kWh. The details of the online bidding process for energy storage devices are presented in Table 3.
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.
This reflects positively that, under the condition of unchanged demand on the load side, the overall utilization rate of small energy storage devices has been improved due to resource optimization and scheduling by the cloud energy storage service provider.
