| 摘要: |
| 目前风电并网运行渗透率逐步增大，利用风电参与电网频率调整，增强系统运行的稳定性已经成为国内外研究的热点问题。综述了风电参与系统频率调整的控制策略研究进展，对比研究了虚拟惯性控制、下垂控制、转子转速控制、桨距角控制、附加储能系统等不同控制策略，明确了各种控制策略的原理、优缺点以及适用范围。分析了风电场内不同风机之间的协调控制算法以及风机与其他常规机组之间的协调配合控制。阐述了智能算法、虚拟同步发电机技术给风电调频带来的新思路以及电压源型高压直流输电技术的应用给风电调频带来的挑战。最后，展望了未来研究的重点内容:源荷双侧的高度不确定性对风电调频的影响；风电调频算法参数整定的依据；风电参与系统调频容量的评估方法。 |

| Abstract: |
| At present, the penetration of wind power integration operation increases gradually. Using wind power to participate power grid frequency regulation and strengthen system operation stability is the research hot topic at home and abroad. This paper reviews the technology development for wind farm participating into power grid frequency regulation and contrastively analyzes different control strategies such as virtual inertia control, droop control, rotor speed control, pitch control and additional energy storage systems. The principle, pros and cons, and applicable range of various control strategies are stated. The coordination control algorithm among different wind turbines in a wind farm and the coordination control between wind turbines and other conventional generators are analyzed. The new thoughts brought by the application of intelligence algorithm and Virtual Synchronous Generator technology (VSG) and the challenges resulted from the application of Voltage Source Converter Based High Voltage Direct Current transmission (VSC-HVDC) in wind power frequency control are studied. Finally, this paper comes up with some key issues to be researched in the future:the impacts of source charge bilateral uncertainty on wind power frequency regulation, the parameters setting basis of wind power frequency modulation algorithms, and frequency regulation capacity evaluation method of wind power in systems. |
