6 FAQs about [Flywheel energy storage power conversion system]

What is a flywheel-storage power system?

A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.

What are flywheel energy storage systems?

Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact.

How does a flywheel work?

After charging, the energy is stored as kinetic energy and maintained in standby mode by allowing the flywheel to spin for as long as possible, minimising any restrictive forces to the rotation. When the energy is needed, the flywheel can then transfer the kinetic energy back to electrical energy via the machine [ 128 ].

What is the operational mechanism of a flywheel?

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 .

Why is a flywheel used as a generator?

This is used when an excess of energy is being produced from an external source, and, therefore, the flywheel stores the energy [ 34 ]. When this stored energy is required, the electrical machine acts as a generator, and the kinetic energy stored in the rotor applies a torque. This is then converted into electrical energy.

What are the potential applications of flywheel technology?

Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
