摘要: 风力发电可以解决能源短缺和环境污染等问题,但由于风速随机性和间歇性的特点导致风电输出电压、功率和频率存在较大波动,因此风电的大规模并网会对现有电网的稳定运行造成不利影响。飞轮储能是一种高效无污染的储能技术,而且通过合理的控制策略和控制设备可实现电网调频及短时间调峰以解决大规模风电并网带来的问题。本文主要介绍了飞轮储能在风力发电领域的应用背景、飞轮储能的结构原理和目前国内外在飞轮储能控制策略方向的研究进展。

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)
