(1) New energy access

Due to the strong randomness, high intermittency, and rapid output changes of new energy sources such as wind and solar energy, direct grid connection of new energy sources, especially large capacity grid connections, will have a certain impact on the scheduling and control of the power grid, and even interfere with the stability of the power grid. By combining battery energy storage systems with renewable new energy, the randomly changing output power is converted into relatively stable output, ensuring the stability of the power grid system.

(2) Backup power supply

In remote areas, areas with poor power supply reliability, or areas with important loads, MW level battery energy storage systems can serve as backup power sources to provide power for power grid systems that fail or distribution systems that require maintenance. The MW level containerized battery energy storage system can be transported to a region and provide localized power sources. When severe weather damages the public power grid system, it can be used for emergency rescue; Or it can be used in areas that are not yet connected to the power grid. The MW level containerized energy storage system can be integrated into the power grid for charging, and can also be configured with new energy access for energy storage and supply.

(3) Microgrid

During the isolated operation of microgrids, the randomness of distributed energy and user loads is significant, making it difficult to ensure real-time balance of power generation and consumption, resulting in a wide range of frequency fluctuations and severe voltage fluctuations. Large capacity and efficient battery energy storage technology can suppress interference from external power grids, ensure the power quality of local users, and further achieve smooth operation of microgrids.
