The battery in electrochemical energy storage is mainly based on lithium iron phosphate batteries. This energy storage battery is largely used in high -voltage energy storage systems of industrial and commercial customers, such as power generation side, transmission and distribution side, user side, etc. The following hailei will explain in detail.

1. User side

(1) Power generation by grid, fluctuate in flatness

     Energy storage batteries can be widely used in wind power and photovoltaic power generation, can smooth the power output fluctuations, reduce its impact on the power system, improve the ability of the power station tracking plan to contribute, and provide spare energy for the construction and operation of renewable energy stations. Bring greater economic benefits to users.

(2) Power grid peak adjustment frequency adjustment

     This is one of the role of energy storage batteries to participate in power grid power regulation, because the auxiliary service of power grid is divided into capacity and power services, capacity -type services such as grid peak adjustment, loading follow -up and black start, etc. Generally, between 1 and 500 mW, the discharge time is greater than 1 hour; power service, such as frequency adjustment assistance and voltage support, requires a large power or voltage output in a short time (minute level). In terms of improving the power grid frequency adjustment capacity, energy storage battery technology can reduce the loss of traditional frequency adjustment power supply due to frequent switching; in terms of improving the power of the grid peak adjustment, according to the changes in the power supply and load, the energy storage system can timely and reliably respond to the scheduling scheduling Instructions, and change their level of contribution based on the instructions. In this case, the peak adjustment effect of the energy storage battery can effectively suppress the peak values.

(3) Peak Valley electricity price difference

      Users on the user side can use an energy storage system composed of energy storage batteries to perform peak -filled valley reclamation and demand side response. For example, energy storage batteries can be used to combine power electronics technology to provide users with reliable power supply and improve the quality of electrical energy; and use the difference between peak and valley electricity prices to save users expenses.

     In summary, these are descriptions of the application scenario of energy storage batteries. With the development of carbon neutrality, energy storage batteries will play an increasing role and in the direction of technology diversified.
