To determine the appropriate size of a flywheel energy storage system, a flywheel energy storage calculator can be used. This calculator takes into account several factors, including the amount of energy that needs to be stored, the rate at which energy needs to be discharged, and the time over which the discharge needs to occur.
The following equations describe the energy capacity of a flywheel: (2) E m = α α α K σ / ρ (3) E v = α α α K σ where α ′ is the safety factor, α ′ ′ the depth of discharge factor, α ′ ′ ′ the ratio of rotating mass to the total system mass, σ the material’s tensile strength, K the shape factor, and ρ the density.
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.
Dai Xingjian et al. designed a variable cross-section alloy steel energy storage flywheel with rated speed of 2700 r/min and energy storage of 60 MJ to meet the technical requirements for energy and power of the energy storage unit in the hybrid power system of oil rig, and proposed a new scheme of keyless connection with the motor spindle.
The amortized capital costs are $130.26 and $92.01/kW-year for composite and steel rotor FESSs, respectively. The corresponding LCOSs are $189.94 and $146.41/MWh, respectively. Table 4. Cost summary for 20 MW/5MWh flywheel energy storage systems.
The flywheel energy storage system mainly stores energy through the inertia of the high-speed rotation of the rotor. In order to fully utilize material strength to achieve higher energy storage density, rotors are increasingly operating at extremely high flange speeds.
