The energy storage system, as its name implies, can collect and store the surplus energy that is not used for a period of time in some way, and then use it at the time and place needed.
Energy storage is an important part of the six links of "production, generation, transmission, distribution, use and storage" in the power production process. Energy storage system can realize energy transfer and promote the application of new energy; Microgrid can be established to provide power for non power areas; It can adjust peak and frequency to improve the stability of power system operation.
Energy storage system is of great strategic significance to the construction of smart grid.
Electric energy storage methods include: battery type energy storage, inductor type energy storage, capacitor type energy storage and other types of energy storage.
The application scenarios of energy storage are diverse, and they are applied at the power generation side, power grid side and power consumption side. In some scenarios, energy storage systems become increasingly indispensable.
