In recent years, the new energy industry has developed rapidly. The application scenarios of lithium-ion batteries can be divided into three categories: consumption, power, and energy storage. Currently, energy storage battery technology is developing rapidly, and the lithium-ion battery energy storage field has also been closely watched. Once a breakthrough is achieved, it will have a significant impact on the development of new energy, grid operation control, and terminal energy use.
I. The uses of lithium-ion battery energy storage systems
As an emerging application scenario, energy storage lithium-ion batteries are gradually receiving attention. With their high energy density, high conversion efficiency, and fast response, lithium-ion batteries have broad prospects in the application of large-scale energy storage systems. In the future, energy storage lithium-ion battery technology will be widely used in the new generation of power systems.
Requirements for new energy grid connection, including improving power quality and smoothing power output; combining with new energy generation curve prediction for tracking new energy generation plans; peak shaving to enable sustained new energy generation; and combining with photovoltaic and wind power generation to smooth power output, increase the grid acceptance rate, fully utilize new energy, and reduce harmful gas emissions.
Adjust the load curve, peak shaving, and improve the utilization of distribution equipment and lines.
Participate in grid frequency regulation to improve the power supply level of the large grid.
As an important part of microgris, solve people's livelihood problems and improve the quality of local power supply.
An important element of smart grids.
Data centers; lithium-ion batteries can be quickly charged and discharged multiple times, and have high density characteristics. They can store electricity during the off-peak period of municipal electricity use and transfer the stored power to data centers when the peak period comes, thereby reducing the peak pressure on the grid. This function will make significant contributions to both green energy saving and PUE, and can simultaneously meet the dual requirements of the government and data center users regarding PUE and TCO.
II.The Significance of Developing Lithium Ion Battery Energy Storage Systems
The application of lithium ion battery energy storage systems can change the traditional energy supply and consumption mode, and is of great significance in promoting energy structural transformation, energy revolution on the consumer side, ensuring energy security, and achieving energy saving and emission reduction targets.
In distributed generation and microgrid systems, wholesale lithium battery system is essential for storing electricity, peak shaving, filling valleys, and stabilizing the output fluctuations of new energy. With the continuous development of lithium ion battery technology and the strong support of countries around the world for lithium ion batteries and new energy technology, large-scale lithium ion battery energy storage systems have been increasingly researched and applied.
The energy storage market includes large-scale electric power storage, home energy storage, and backup power storage. Under existing technologies, the cost-effectiveness of lithium ion batteries in the field of backup power storage has significantly improved, and backup power and home energy storage are currently more suitable applications for lithium ion batteries. Among them, energy storage, especially backup power storage, has a vast market potential. The future market potential of lithium ion battery energy storage is unlimited.
With the development and widespread application of various lithium ion battery energy storage technologies in the future, energy storage batteries will be applied to various aspects of the power system, such as generation, transmission, distribution, usage, and regulation. This could change the production, transportation, and use of the existing power system, and assist the traditional power system in transforming into a new generation power system that is widely interconnected, intelligent, interactive, flexible, safe, and controllable.
New energy storage battery technologies have become a hot spot and technological frontier in current research and development, and in the future are expected to greatly improve the performance of custom energy storage systems and promote the large-scale application of energy storage lithium ion batteries.
