Flywheel energy storage systems (FESS) store energy in a rotating mass. The advantages of such systems includes high power density, environmental friendliness, long lifespan, wide operating temperature range, and very long charge-discharge cycle life. FESS has therefore been widely used in numerous applications. Integrating multiple flywheel energy storage units to form a flywheel array energy storage system (FAESS) provides a mean for large scale energy storage. In this paper, an overview of the current development status and key technologies of FAESS is given. Design method, parallel topology and control strategy of FAESS are then presented. With enhanced control technologies for parallel operation of flywheel energy storage units, FAESS could be used for grid frequency regulation particularly for dealing with intermittent renewable energy generation.
