   distributed energy system consists of distributed power generation unit, energy storage equipment, smart grid and so on. Its core is to improve the absorption ratio and overall energy supply quality of renewable energy. However, the intermittent power generation and fluctuation of renewable energy lead to the instability and unpredictability of the energy system, and the application of energy storage technology has become an effective way to solve this problem. As an important part of distributed energy system, lithium storage battery can store redundant renewable energy to cope with load fluctuation, peak-Valley balance and other problems and improve energy utilization efficiency.

3. Function and significance of lithium battery for energy storage
   in the distributed energy system, lithium storage battery plays the role of "smart warehouse. First of all, lithium battery for energy storage can smooth the fluctuation of renewable energy, store excess energy in case of emergency, and improve the stability and reliability of the system. Secondly, the energy storage lithium battery can realize peak and valley filling, that is, release the stored energy at the peak of electricity consumption, and charge at the low power consumption to realize the rational distribution and utilization of energy. In addition, lithium battery energy storage can also provide standby power supply and frequency modulation service, providing flexible support for power grid operation.

4. Technology development and application prospect
   with the continuous development and maturity of energy storage technology, the application prospect of lithium storage battery in distributed energy system is very broad. In the future, with the continuous reduction of energy storage technology cost and the continuous improvement of performance, energy storage lithium batteries are expected to become the main force in distributed energy systems, providing strong support for the large-scale consumption of renewable energy. At the same time, with the deepening of concepts such as smart grid and energy internet, lithium battery for energy storage will also play a wider role, providing technical support for intelligent operation of energy system.

We can see that lithium battery for energy storage plays an important role in distributed energy system, and its function and significance cannot be ignored. In the development process of distributed energy system, lithium battery for energy storage will become an indispensable component, providing important support for intelligent operation of energy system, promote the efficient utilization of renewable energy and the development of clean energy. It is believed that with the continuous progress of technology and the accumulation of application experience, the application prospect of lithium storage battery in distributed energy field will be broader and brighter.
