Energy storage in a flywheel is realized by a spinning mass in the form of kinetic energy [144,145]. The flywheel energy storage system is mainly composed of a rotor, magnetic bearing systems, a vacuum housing and an electric machine [142,145].
Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
The operational mechanism of a flywheel has two states: energy storage and energy release. Energy is stored in a flywheel when torque is applied to it. The torque increases the rotational speed of the flywheel; as a result, energy is stored. Conversely, the energy is released in the form of torque to the connected mechanical device .
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.
Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
The basic function of the flywheel is to convert the mechanical energy for the end-use application, which is electrical energy. For this conversion, an electromechanical machine is required which could be a motor/generator set. Generator and motor: When the kinetic energy is being stored, the motor is used to drive the flywheel.
