摘要

为科学合理地分配风电场调频功率和降低减载调频弃风量，首先，根据风电机组（WTs运行状态，将WTs分为不可调频、降功率调频和升功率调频3类，并在此基础上，结合系统调频功率（降功率或升功率）需求，选取对应WTs调频，避免所有WTs同时参与调频，进而降低WTs调频动作次数，延长寿命；其次，根据WTs运行状态和极限，构建WTs减载约束模型来定义其调频能力，进而实现WTs调频功率优化分配和弃风容量优化利用的双重目的，并通过定义WTs退出调频风险指标，使得WTs有序退出调频，避免了系统频率二次跌落问题。仿真研究表明：考虑不同运行状态下WTs调频能力差异来优化分配调频功率，可提升系统调频能力和弃风利用率。

Abstract

To scientifically and reasonablely distribute wind farm frequency regulation power and reduce load reduction frequency regulation abandoned wind volume

wind turbines(WTs) are divided into three types: no frequency modulation(FM)

down-power FM

and up-power FM

according to the operating status of WTs. On this basis

combining with the system modulation power(down power or up power) requirements

the corresponding WTs frequency regulation is selected to avoid all WTs participating in frequency regulation at the same time

thus to reduce the frequency of WTs frequency regulation and prolong the unit life. Secondly

according to the operating status and limit of WTs

the load shedding constraint model of WTs is constructed to define its frequency regulation capability

so as to realize the dual purpose of optimal allocation of WTs frequency regulation power and optimal utilization of wind curtailment capacity

which can effectively solve the problems caused by average allocation

make WTs quit frequency regulation orderly by defining the risk index of WTs quitting frequency regulation

and avoid the system frequency drop twice problem. The simulation results show that

considering the difference of WTs frequency regulation capability under different operating states to optimize the allocation of frequency regulation power can improve the frequency regulation capability and utilization rate of wind abandoning.
