摘要

为兼顾系统在不同频率支撑阶段的频率跌幅,提出一种基于权衡频率极值点的风电频率支撑控制参数配置方法。首先,定性分析风电频率支撑控制参数对系统频率动态响应的影响;其次,推导出考虑同步机与风电参与频率支撑的系统频率动态响应模型的时域表达式,统一不同阻尼比时频率极值点的计算式;随后,基于频率响应模型分析风电机组退出频率支撑时系统所遭受的功率扰动量,得到量化评估风电机组转速恢复阶段系统频率极值点的计算方法;基于此,以最小化系统频率支撑阶段所有频率极值点为目标建立优化模型配置风电频率支撑控制参数。最后,仿真算例验证该方法可在不同风电占比场景下配置频率支撑参数,在保证风电机组频率支撑强度的同时不会因过度释放频率支撑动能而造成严重的系统二次跌落。

Abstract

To address frequency drops in the power system during various frequency support intervals, this paper proposes a method for setting frequency support control parameters for wind power based on weighing frequency extreme points. First, we qualitatively analyze how frequency support control parameters of wind power impact the system’s dynamic frequency response. Next, we derive the time-domain expression for the system frequency dynamic response model, taking into account the contributions of synchronous generators and wind power during frequency support. We also investigate how different damping ratios affect the accuracy of the time-domain analytical formula. Subsequently, we analyze the power disturbances experienced by the system when wind turbines exit frequency support, developing a calculation method to evaluate the system’s frequency extreme points during the rotational speed recovery period of wind turbines. Based on this analysis, we establish an optimization model aimed at setting frequency support control parameters that minimize all frequency extreme points during the frequency support intervals. Finally, case studies validate that the proposed method can effectively set frequency support parameters according to varying wind power proportions, ensuring the frequency support capability of wind turbines without causing significant secondary frequency drop in the system due to excessive release of kinetic energy during frequency support.
