The guarantee system is stable, and the energy storage system can still run at a stable output level even when the load fluctuates rapidly.

Energy is used for backup, and the energy storage system can play a spare and transitional effect under the condition of clean energy power generation.

Improve the quality and reliability of electricity. The energy storage system can also prevent the power grid fluctuation caused by the voltage peak, voltage decline, and external interference on the load. reliability.

The application of energy storage in the power system can make up for the lack of storage and release functions in the power system. It is the key to ensuring the large -scale development of clean energy and the operation of the power grid's security economy. Energy storage has become more flexible in changing the scale of electric energy production, transportation, and use of synchronous completion, which makes the rigid power system more flexible, especially in terms of volatility brought by the volatility of large -scale clean energy power generation to the power grid.
