What is flywheel energy storage system (fess)?

Flywheel Energy Storage System (FESS) can be applied from very small micro-satellites to huge power networks. A comprehensive review of FESS for hybrid vehicle, railway, wind power system, hybrid power generation system, power network, marine, space and other applications are presented in this paper.

Can flywheel energy storage improve wind power quality?

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.

What are the potential applications of flywheel technology?

Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

How to increase the energy storage density of flywheel rotors?

To increase the energy storage density, one of the critical evaluations of flywheel performance, topology optimization is used to obtain the optimized topology layout of the flywheel rotor geometry.

What determines the performance of energy storage Flywheel?

The performance of the energy storage flywheel is basically determined by the rotor material properties, geometry and rotating speed. A high density material can significantly increase the rotor mass and hence increase the stored kinetic energy of flywheel.

Can topology optimization improve energy storage Flywheel design?

These optimized flywheels obtained by topology optimization can provide a valuable guidance for the energy storage flywheel design in practical engineering. A high speed rotating flywheel can store enormous kinetic energy serving as an important type of energy (Bitterly 1998 ).
