Flywheel Energy Storage System (FESS) , which stores energy in a rotating mass, is now considered a promising technology for many applications due to its significant advantages versus chemical batteries. Integrating multiple modular FESS units to form a FESS array is a suitable solution to attain large capacity energy storage. This paper presents a FESS array topology for an uninterruptible power...
Flywheel energy storage has fast charge and discharge speed, and it is capable of discharge huge power in a very short time. So it has become a wise choice to solve power quality problems. This paper describes a Dynamic Voltage Restorer (DVR) using flywheel energy storage (FES) to protect the critical load from voltage sags in distribution network. The flywheel unit is composed of high strength steel...
Flywheel energy storage has attracted new research attention recently in applications like power quality, regenerative braking and uninterruptible power supply (UPS). As a sustainable energy storage method, flywheel energy storage has become a direct substitute for batteries in UPS applications. Inner design of the flywheel unit is shown to illustrate the economical way to construct the system. A...
