Abstract
A flywheel energy storage systems (FESS) is suitable for high-power, low-energy content to deliver or absorb power in surges. This type of application is very suitable for frequency regulation in an electric grid. In addition, a modern FESS is built as a high-efficiency, high-speed motor/generator drive system that employs modern power electronics, therefore, the power quality of the grid-connected output is excellent. In addition, a FESS is very valuable to delivering ancillary services to the grid, and it can contribute reactive power compensation. Thus, a FESS can maintain high reliability in power systems by providing ride-through capability to the power system area while the rest of the generating fleet, which has a slower response in the power system, performs primary and secondary frequency response to the grid. A FESS has several advantages compared to a chemical-based energy storage (CBES) system, namely: it has high energy density and durability, and it can be cycled frequently without impacting performance. The response of FESS is faster than that of a CBES. Also, unlike some CBES, FESS has the same performance regardless of the number of cycles of charging/discharging performed throughout its lifetime.
