Generally, electric energy cannot be stored (the current battery energy storage is high in cost and limited in energy storage), so that the electric power plant needs to synchronously generate electric energy according to the electric energy required by a user, and energy is not wasted. However, in general, the electrical load in the power system is constantly changing, and in order to maintain the active power balance and keep the system frequency stable, the power generation department needs to correspondingly change the power generation amount of the generator to adapt to the change of the electrical load, which is called peak shaving.
In the three northeast areas of China, peak-shaving power supplies such as gas turbines and pumped storage are scarce, contradiction between renewable energy power generation and insufficient flexibility of thermal power generating units is prominent, the power grid has insufficient capacity of absorbing new energy such as wind power, photoelectricity, hydropower and nuclear power, the phenomena of wind abandonment, light abandonment, water abandonment and nuclear power abandonment are serious, and the peak-shaving requirement of the power grid is strong.

However, the current flow electric fuel has low energy density and complicated battery replacement operation, and if the battery replacement can be conveniently realized by using a charge-discharge battery in a fluid state, the electric automobile in a battery rental or replacement mode can be more feasible in the future.
The redox flow battery is different from a conventional solid battery or a conventional redox flow battery, and the redox flow battery charger and the redox flow battery work independently, so that the storage and the release of fluidized electric energy can be realized. The method is applied to the electric automobile, can provide longer endurance mileage, can realize that the charging process of the battery is a refueling process (full-electricity electric fuel injection), and can be completed within a few minutes.
