Abstract: Wind power is generation is characterized by large extents of fluctuations in power quality and frequency stability due to the randomness and intermittence of wind speed and direction. Large-scale applications of wind power have a great impact on the stability of electrical grids. Compared with other energy storage technologies, flywheel energy storage (FES) has advantages of high round-trip efficiency and little environmental impact. FES is capable of helping low voltage ride through and smooth power output with appropriate control strategies and electronic control devices. FES can also enhance frequency stability and improve power quality of wind generator delivered to the grid. This paper introduces the background of the use of FES in wind power, explains the principles of FES, and reviews current status in the control strategies of FES.

Key words: flywheel energy storage (FES), wind power, control strategy, power smoothing, low voltage ride through (LVRT)
