The magnetically suspended flywheel energy storage system (MS-FESS) is an energy storage equipment that accomplishes the bidirectional transfer between electric energy and kinetic energy, and it is widely used as the power conversion unit in the uninterrupted power supply (UPS) system.
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.
A 10 MJ flywheel energy storage system for high quality electric power and reliable power supply from the distribution network, was tested in the year 2000. It was able to keep the voltage in the distribution network within 98%–102% and had the capability of supplying 10 kW of power for 15 min .
D. Power Electronics The flywheel energy unit produces variable frequency AC current. To reliably operate the system, power electronics devices must be installed in order to keep the frequency constant so that it can be connected to the grid. Power converters for energy storage systems are based on SCR, GTO or IGBT switches.
Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .
