Structure diagram of flywheel energy storage system

What are the components of a flywheel energy storage system?

A flywheel energy storage system consists of bearings, a rotating mass, a motor-generator, and a frequency inverter. Fig. 14.4 shows the main components of a flywheel energy storage system . The design of the components influences the overall efficiency, and can help in reducing power transmission losses.

How does Flywheel energy storage work?

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.

What is a flywheel energy storage system (fess)?

Modern flywheel energy storage system (FESS) only began in the 1970’s. With the development of high tense material, magnetic bearing technology, permanent magnetic motor, power electronics and advanced control strategy, FESS regains interests from many research organizations and companies, such as NASA’s GRC, US Army and Active Power Inc.

Are flywheel energy storage facilities suitable for continuous charging and discharging?

The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .

Which method is used in flywheel energy storage system?

Another method used in flywheel energy storage systems is to store energy with high speed. In this method the rotating object is rotated up to 100,000 rpm . The rotating object weight is low in this method. This method is used in small applications in terms of volume and weight.

Why do flywheel energy storage systems have a high speed?

There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
