Flywheel energy storage systems (FESS) are considered environmentally friendly short-term energy storage solutions due to their capacity for rapid and efficient energy storage and release, high power density, and long-term lifespan. These attributes make FESS suitable for integration into power systems in a wide range of applications.
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 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.
