This paper gives a review of the recent developments in FESS technologies. Due to the highly interdisciplinary nature of FESSs, we survey different design approaches, choices of subsystems, and the effects on performance, cost, and applications. This review focuses on the state of the art of FESS. . In 2017,HHEin flywheel energy storage manufacturers in China won the bid for the flywheel UPS project with a large order of nearly 100 million RMB,and successfully delivered a 16MW dynamic flywheel UPS system in 2018. Flywheel energy storage system is an energy storage device that converts mechanical energy into electrical energy, breaking. . Another significant project is the installation of a flywheel energy storage system by Red Eléctrica de España (the transmission system operator (TSO) of Spain) in the Mácher 66 kV substation,located in the municipality of Tías on Lanzarote (Canary Islands). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact.
