The small energy storage composite flywheel of American company Powerthu can operate at 53000 rpm and store 0.53 kWh of energy . The superconducting flywheel energy storage system developed by the Japan Railway Technology Research Institute has a rotational speed of 6000 rpm and a single unit energy storage capacity of 100 kW·h.
In the future, the focus should be on how to improve the stability of the flywheel energy storage single machine operation and optimize the control strategy of the flywheel array. The design of composite rotors mainly optimizes the operating speed, the number of composite material wheels, and the selection of rotor materials.
Therefore, the selection of appropriate rotor materials and the design of rotor structure are the key to reducing the cost of flywheel energy storage, which is crucial for the promotion of flywheel energy storage. Several review papers address different aspects of FESS research.
The flywheel is the main energy storage component in the flywheel energy storage system, and it can only achieve high energy storage density when rotating at high speeds. Choosing appropriate flywheel body materials and structural shapes can improve the storage capacity and reliability of the flywheel.
Arvin et al. used simulated annealing method to optimize the structure of composite flywheel and optimized the energy storage density of flywheel energy storage system by changing the number of flywheel layers.
Among them, the rupture of the flywheel rotor is undoubtedly the most destructive flywheel energy storage system failure. Therefore, in the design process of flywheel rotor, it is necessary to fully evaluate the operation safety of flywheel energy storage system based on the material, size, and speed of the rotor.
