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.
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
Flywheel Systems are more suited for applications that require rapid energy bursts, such as power grid stabilization, frequency regulation, and backup power for critical infrastructure. Battery Storage is typically a better choice for long-term energy storage, such as for renewable energy systems (solar or wind) or home energy storage.
Permanent-Magnet Motors for Flywheel Energy Storage Systems The permanent-magnet synchronous motor (PMSM) and the permanent-magnet brushless direct current (BLDC) motor are the two primary types of PM motors used in FESSs. PM motors boast advantages such as high efficiency, power density, compactness, and suitability for high-speed operations.
Energy Storage: The flywheel continues to spin at high speed, maintaining energy as long as friction and resistance are minimized. The longer it spins, the more energy it holds, similar to how the skater retains rotational energy as they keep spinning.
Here’s a breakdown of the process: Energy Absorption: When there’s surplus electricity, such as when the grid is overproducing energy, the system uses that excess power to accelerate the flywheel. This energy is stored as kinetic energy, much like how the figure skater speeds up their spin by pulling in their arms.
