Thanks to the power electronics and composite material technology, the flywheel energy storage system performances are increasing. In conventional flywheel energy storage systems, a motor is connected to a rotating mass shaft and the motor performs energy storage. Energy is taken with another generator connected to the rotating mass (discharge).
Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
Flywheel energy storage systems have a long working life if periodically maintained (>25 years). The cycle numbers of flywheel energy storage systems are very high (>100,000). In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety.
There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system. The high speeds have been achieved in the rotating body with the developments in the field of composite materials.
Another significant project is the installation of a flywheel energy storage system by Red Eléctrica de España (the transmission system operator (TSO) of Spain) in the Mácher 66 kV
