摘要(Abstract)：

风电渗透率的提高,使电网惯性及相对备用容量降低,对电网负荷频率控制带来新的挑战,风机参与电力系统频率调节的研究为解决上述问题提供了新的途径。首先,基于风机单机模型,提出了快速动能提取的惯性控制方法,并探讨了其与桨距角控制的互补性,通过惯性调整最大化,为减少风机桨距角调节负担提供支持;其次,在电力系统有功缺额及风机调频能力边界分析的基础上,提出了风机桨距角参与调频的驱动策略,旨在降低桨距角参与调频的程度,并减少风机参与调频过程中桨距角调节的次数。仿真结果说明,在满足电网调频要求的情况下,所设计的控制方法可最大限度地减小桨距角调整的幅度及频次,并有效提高电网调频效果。

关键词(KeyWords)： 电网频率;风机有功控制;边界分析;次优功率控制;桨距角控制
