Lithium battery packs play multiple key functional roles in energy storage power stations. The following is a detailed analysis of their functional roles:

First, electrical energy storage and release

Electrical energy storage: Lithium battery packs can efficiently store electrical energy, which is their most fundamental and important function. In photovoltaic power generation systems, lithium battery packs can store the excess electrical energy generated during the day for use at night or when there is insufficient light.

Power release: When power is needed, the lithium battery pack can quickly release the stored power to supply power to the load. This rapid response capability enables lithium battery packs to play a crucial role in energy storage power stations.

Second, peak shaving and valley filling as well as electricity fee management

Peak shaving and valley filling: Lithium battery packs can store electrical energy during off-peak hours and release it during peak hours, thereby reducing the peak electricity consumption of enterprises and alleviating the load on the power grid.

Electricity bill management: By peak shaving and valley filling, enterprises can save a significant amount of electricity bills and optimize electricity usage costs. Meanwhile, lithium battery packs can also participate in peak-valley electricity price arbitrage transactions in the power market to obtain additional economic benefits.

Third, improve energy utilization efficiency

Smooth output power: Lithium battery packs can smooth the output power of photovoltaic power stations, reduce power fluctuations, and enhance the stability and reliability of the power grid.

Stable power supply: For areas without electricity, with insufficient power supply, or regions with inadequate grid coverage, lithium battery packs can serve as independent energy supply systems, providing stable and reliable power supply for local residents and small businesses.

Fourth, emergency power supply guarantee

Emergency power supply: In the event of a power outage in the power grid, the lithium battery pack energy storage system can serve as an emergency power source, continuously supplying power to critical loads such as lighting, refrigerators, and communication equipment in households, enterprises, or important facilities, ensuring basic living needs and emergency communication.

Fast switching: Lithium battery packs have a rapid charging and discharging response capability, which can adjust the charging and discharging power in an instant according to the demand of the power grid or changes in load, achieving flexible support for the power grid and power regulation.

Fifth, grid ancillary services

Frequency and voltage regulation: Lithium battery pack energy storage systems can participate in the frequency and voltage regulation services of the power grid, improving the power quality and power supply reliability of the power grid.

Reactive power compensation: By rationally configuring lithium battery pack energy storage systems, reactive power compensation functions can also be achieved, further enhancing the stability and efficiency of the power grid.

Sixth, promote the consumption of renewable energy

Solving intermittent problems: Lithium battery pack energy storage systems can effectively address the intermittency and instability issues of new energy sources such as wind power and photovoltaic power generation, ensuring the stable output and efficient utilization of renewable energy.

Increasing the consumption ratio: By storing excess electricity and releasing it when needed, lithium battery pack energy storage systems help increase the consumption ratio of renewable energy in the power grid, promoting the development and application of clean energy.
