Energy storage is performed by radius and weight parameters in this method. Fig. 7.8 shows the integration of the flywheel energy storage system with the grid. In this method the stored energy is transferred to the grid by a generator, alternative current (AC)/direct current (DC) rectifier circuit, and DC/AC inverter circuit. Figure 7.8.
Think of it as a mechanical storage tool that converts electrical energy into mechanical energy for storage. This energy is stored in the form of rotational kinetic energy. Typically, the energy input to a Flywheel Energy Storage System (FESS) comes from an electrical source like the grid or any other electrical source.
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia. Whenever power is required, flywheel uses the rotor inertia and converts stored kinetic energy into electricity .
The minimum speed of the flywheel is typically half its full speed, the storage energy is be given by ½ (12-0.52) Ifwf2 where If is the rotor moment of inertia in kgm2 and the wf maximum rotational speed in rad/s. The power level is controlled by the size of the M/G, so this is independent of the rotor.
In simple terms, a magnetic bearing uses permanent magnets to lift the flywheel and controlled electromagnets to keep the flywheel rotor steady. This stability needs a sophisticated control system with costly sensors. There are three types of magnetic bearings in a Flywheel Energy Storage System (FESS): passive, active, and superconducting.

ESSs store intermittent renewable energy to create reliable micro-grids that run continuously and efficiently distribute electricity by balancing the supply and the load [1].
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
