What is a flywheel/kinetic energy storage system (fess)?
Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
How does a flywheel drive system work?
Charging: In this process, the consumed electric energy is converted into the mechanical energy of the flywheel rotation, the drive motor operates as a motor, and the speed of the drive motor is also increased until it reaches the rated speed. The power system delivers electrical energy to the flywheel device.
What are the application areas of flywheel technology?
Application areas of flywheel technology will be discussed in this review paper in fields such as electric vehicles, storage systems for solar and wind generation as well as in uninterrupted power supply systems. Keywords - Energy storage systems, Flywheel, Mechanical batteries, Renewable energy. 1. Introduction
