Free QuoteThe 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.
The power system delivers electrical energy to the flywheel device. Discharge: The process converts the mechanical energy consumed by the rotation of the flywheel into electrical energy and transmits it out, the drive motor operates as a generator, and the speed of the flywheel will decrease accordingly.
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 .
In a 9-megawatt energy storage project, six flywheels have been installed in combination with a large battery to create an innovative hybrid storage system in Heerhugowaard, around 35 kilometers from Amsterdam.
Based on this technology, a 50 kWh energy flywheel rotor system was designed and produced, with a rotor height of 1250 mm and an outer 900 mm. Alternative rotor systems of the same diameter have successfully reached 17,000 rpm, exceeding the design speed by 15,000 rpm.
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.
