The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
With this FESS, 66% of the brake energy can be stored and reused in the best conditions. In vehicles, a flywheel is specifically weighted to the vehicle’s crankshaft to smooth out the rough feeling and to save energy. In city buses and intercity taxis, it can have a huge impact on reducing fuel consumption.
Still, many customers of modern flywheel energy-storage systems prefer to have them embedded in the ground to halt any material that might escape the containment vessel. An additional limitation for some flywheel types is energy storage time. Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in 2 hours.
A dynamic model of an FESS was presented using flywheel technology to improve the storage capacity of the active power distribution system . To effectively manage the energy stored in a small-capacity FESS, a monitoring unit and short-term advanced wind speed prediction were used . 3.2. High-Quality Uninterruptible Power Supply
Flywheel Bearings The energy storage capacity of an FESS can be enhanced by increasing the speed and size of the flywheel rotor. However, a significant limitation of FESSs comes from the bearings that support the flywheel rotor.
They are also less potentially damaging to the environment, being largely made of inert or benign materials. Another advantage of flywheels is that by a simple measurement of the rotation speed it is possible to know the exact amount of energy stored.

Flywheel Energy Storage
Flywheel energy storage systems using mechanical bearings can lose 20% to 50% of their energy in 2 hours. Much of the friction responsible for this energy loss results from the flywheel changing orientation due to the rotation of the earth (a concept similar to a Foucault pendulum).

Flywheel energy storage
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel. Most FES systems use electricity to accelerate and decelerate the flywheel, but devices that directly use mechanical energy are being developed.
