摘要
随着可再生能源渗透率迅速提升,电网对风电等可再生能源参与系统调峰调频的需求逐渐增强。目前已有大量文献着眼于风电参与一次调频的研究,然而面向风电参与一次调频时机组疲劳损伤的研究尚少。针对限功率工况下风电机组一次调频疲劳损伤抑制展开研究,搭建考虑疲劳指标的机组控制模型和考虑尾流、湍流的风场模型,在此基础上设计分布式控制框架和优化方案,对一次调频过程中的风电场进行功率优化调度。仿真结果表明,风电场参与一次调频对机组结构会带来一定程度的疲劳上升,所提方案则可以明显降低这一不利影响,为风电场更经济地进行电网辅助调频提供理论和应用基础。
With rapid increase of renewable energy,the power grid has gradually increased the demand for wind power to participate in the peak and frequency regulation. At present,many literatures focus on the primary frequency regulation of wind power,but there are few studies on the fatigue damage of wind turbines during the primary frequency regulation. This paper studies the fatigue damage suppression of wind turbines during primary frequency regulation and builds the generating unit control model considering the fatigue index and the wind field model considering the wake and turbulence. On this basis,the distributed control framework is used to optimize the power dispatch. The results show that the wind farm’s participation in primary frequency regulation will bring a certain degree of the fatigue rise to the unit structure. The scheme proposed in this paper can significantly reduce this adverse effect and provide a theoretical and application basis for wind farms to conduct frequency regulation more economically.
