Applications of lithium-ion battery energy storage systems
Lithium-ion batteries for energy storage are gaining increasing attention as an emerging application. With their high energy density, high conversion efficiency, and fast response, lithium-ion batteries hold great promise for large-scale energy storage systems. In the future, lithium-ion battery technology for energy storage will be widely used in next-generation power systems.
1. Grid connection needs of new energy sources, including power quality improvement and smoothing; tracking of new energy power generation plans and combining them with power generation curve forecasting; peak shaving and valley filling to ensure continuous power generation from new energy sources; integration with photovoltaic and wind power generation to smooth power output, increase the grid's acceptance ratio, fully utilize new energy sources, and reduce harmful gas emissions;
2. Adjust the load curve to smooth peak loads and fill valleys, thereby improving the utilization rate of power distribution equipment and lines;
3. Participate in power grid frequency regulation to improve the power supply level of the large power grid;
4. As an important component of microgrids, it addresses livelihood issues and improves power supply quality in localized areas;
5. Key elements of smart grids;
6. Special applications (photovoltaic power stations, disaster sites, subway stations, airports, docks, military bases, and other locations requiring uninterrupted power supply)
7. Data Centers: Lithium-ion batteries, with their ability to be rapidly charged and discharged multiple times and their high-density characteristics, can store electricity during off-peak hours in municipal power consumption. When peak demand arrives, the stored power is then transferred to the data center, thus reducing peak pressure on the power grid. This function significantly contributes to both energy conservation and Power Usage Effectiveness (PUE), simultaneously meeting the dual requirements of governments and data center users regarding PUE and Total Cost of Ownership (TCO).
8. Distributed energy storage for peak shaving and valley filling in factories and buildings;
9. Backup power supply.
