Dai Xingjian et al. designed a variable cross-section alloy steel energy storage flywheel with rated speed of 2700 r/min and energy storage of 60 MJ to meet the technical requirements for energy and power of the energy storage unit in the hybrid power system of oil rig, and proposed a new scheme of keyless connection with the motor spindle.
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.
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.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
In 1999 , the University of Texas at Austin developed a 7-ring interference assembled composite material flywheel energy storage system and provided a stress distribution calculation method for the flywheel energy storage system.
Due to the advantage of flywheel, minimizing the operation times of BESS and giving priority of flywheel to respond the fluctuations is proved to be an available option to improve the life span of BESS, reduce the probability of explosion of BESS and secure operation of the hybrid energy storage system.
