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 a flywheel work?

A flywheel is driven by a reversible electric machine that initially operates as a motor to supply energy to the inertial mass. With the drive system disconnected, the flywheel stores energy in its rotation. Upon request, this latter will be transformed into electrical energy by the generator.

How does a flywheel store energy?

The flywheel stores energy by spinning at high speeds and releases it when needed by converting kinetic energy into electrical energy . A power electronic converter is the link between the flywheel motor and the power supply system. The kinetic energy stored in the flywheel is presented in Eq. (1).

How does a high-speed rotating flywheel work?

The system achieves energy conversion and storage between electrical energy and the mechanical kinetic energy of the high-speed rotating flywheel through a bidirectional electric motor/generator, and is connected to different types of loads through frequency modulation, rectification, constant voltage, and interfaces .

How does a flywheel accelerate and decelerate?

A flywheel accelerates as energy is absorbed and decelerates when energy is delivered back to the system. The stored energy is the sum of the kinetic energy of the individual mass elements make up the flywheel. In order to optimize the energy-to-mass ratio, a flywheel needs to spin at its maximum possible speed (Freris, 1990).
