(1) Can be used to eliminate low-frequency oscillation in the power system, used to stabilize the frequency and voltage of the system;

(2) can be used for reactive power control and power factor regulation to improve the stability of the transmission system and power transmission capacity;

(3) Because it can quickly add or absorb active power to the grid, a system with superconducting energy storage batteries can be regarded as a flexible AC transmission system;

(4) If it is not only regarded as an energy storage battery installation, but also as an active power source when the system is operated and controlled, it will be more useful and effective, so it can be used as a superconducting energy management system;

(5) It has an automatic power generation control function in the AGC system, and the local control error can be minimized;

(6) Can be used in power distribution systems or large load sides to reduce fluctuations and balance peak loads, control primary power and improve transient stability, and can get good benefits;

(7) Can be used for island power supply system, because the cost of island and mainland networking is high, generally the gas turbine independent power generation and network, superconducting energy storage battery can be installed to adjust the load;
