What is energy storage? It is an important part of the "mining-development-transportation-distribution-use-storage" in the process of power production. The energy storage system can realize the application of energy to promote the application of new energy; it can establish a micro -grid to provide electricity for power -free regions; peak adjustment and frequency adjustment can be implemented to improve the stability of the power system operation. The battery energy storage system has important strategic significance for the construction of smart grids.

The method of electrical energy storage includes battery storage, inductive energy storage, capacitive energy storage, and other types of energy storage.

Battery energy storage system

It is a system that uses lithium battery/lead battery as a energy storage carrier, and stores and supply electrical energy within a certain period of time. The electrical energy provided has functions such as smooth transition, peak -cutting valley, and frequency regulation and pressure regulation.

Inductive energy storage: Using its own as an energy storage element, the stored power stored is proportional to its inductance and the current flowing by its own current: E = L*I*I/2. Because the inductance has resistance at room temperature and consumes energy, many energy storage technologies use superconductors. Energy storage inductor is not mature and less applications;

Battery energy storage system: It is also an energy storage element. The storage power is proportional to the square of its capacitance and end voltage: E = C*U*U/2. Capacitor storage energy is easy to maintain and does not require superconductors. Super capacitor uses the characteristics of capacitor energy storage to provide instantaneous high power, which is suitable for applications such as laser and flash.
