Customer ServiceWith 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.
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.
User-side shared energy storage is composed of interconnection and mutual benefit of adjacent energy storage devices in the same area, so the power loss in the power interaction process can be ignored 17.
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.
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.
