Learn MoreFlywheel storage energy system is not a new technology; however, the deep interest in applying its principle in power system applications has been greatly increasing in the recent decades.
The flywheel energy storage system (FESS) cooperates with clean energy power generation to form “new energy + energy storage”, which will occupy an important position among new energy storage methods.
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
To enhance the frequency regulation capability of the FESS, some frequency regulation control strategies for wind-power systems with a flywheel energy storage unit have been proposed ( Peralta et al., 2018, Jia et al., 2022, Yulong et al., 2022, Yao et al., 2017 ).
At full speed, the flywheel has 5 kW h of kinetic energy, and it can provide 3 kW of three-phase 208v power to a power load. Small versions of this flywheel will be able to operate at very high speeds, and may require the inherent low losses in HTS bearings to achieve these speeds .
Flywheel systems are composed of various materials including those with steel flywheel rotors and resin/glass or resin/carbon-fiber composite rotors. Flywheels store rotational kinetic energy in the form of a spinning cylinder or disc, then use this stored kinetic energy to regenerate electricity at a later time.
