Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly …

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy …

This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.

A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.

5.1 Flywheel Storage Systems. The first known utilization of flywheels specifically for energy storage applications was to homogenize the energy supplied to a potter wheel. Since a potter requires the involvement of both hands into the axisymmetric task of shaping clay as it rotated, the intermittent jolts by the potter foot meant that the ...

In this paper, we propose a new flywheel energy storage system based on a doubly fed induction machine and a battery for use with microgrids. The new flywheel energy storage system can be used not only to mitigate wind power fluctuations, but also to control the frequency as well as the voltage of the microgrid during islanded operation.

Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical rechargeable batteries. They are also less potentially damaging to the environment, being largely made of inert or benign materials. Another advantage of flywheels is that by a simple measurement of the rotation speed it is possible to know the exact amount of energy stored.
