As a vital energy conversion equipment, the flywheel energy storage system (FESS) [, , , , ] could efficiently realize the mutual conversion between mechanical energy and electrical energy. It has the advantages of high conversion efficiency [6, 7], low negative environmental impact [8, 9], and high power density [10, 11].
A high-temperature superconducting flywheel energy storage system (SFESS) can utilise a high-temperature superconducting bearing (HTSB) to levitate the rotor so that it can rotate without friction [ 1, 2 ].
The high-speed rotating flywheel drags the motor to generate electricity, which can output the current and voltage suitable for the load by the power converter. So, the mechanical kinetic energy stored in the flywheel (or rotor) is converted into electrical energy. In this process, the speed of the flywheel continues to drop.
The rotational speed of the flywheel (FW) rotor is accelerated to the rated value at the charging state of the FESS, and the electrical energy on the grid is transferred to mechanical energy [, , ].
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
