摘　　要：大量电动汽车充电站、城轨交通等冲击性负载接入配电网会对电网的电压和频率产生影响,降低供电的可靠性,飞轮储能凭借快充快放特性并结合合理的控制策略能够很好的消除冲击性负载对电网的影响。简要介绍飞轮储能的工作模式和技术原理,重点分析直流冲击性负载和交流冲击性负载下飞轮储能系统的控制策略,并展望了基于微分反馈环节和控制成本的控制策略发展前景。A large number impact loads as electric vehicle charging station,urban rail transit connected to the distribution network have an impact on the voltage and frequency of the power grid,and reduce the reliability of power supply.Flywheel energy storage can eliminate the impact of shock loads on the power grid by the characteristics of quick charge and discharge combined with a reasonable control strategy.The paper briefly introduces the working mode and technical principle of flywheel energy storage,focuses on analyzing the control strategy of flywheel energy storage system under DC impact loads and AC impact loads,and prospects the development prospect of control strategy based on differential feedback link and control cost.
