摘要

为定量评估混合型新能源场站接入的送端电网频率支撑性能

首先利用频率特性传递函数分别对单馈入跟网/构网型新能源系统调频单元进行参数整定

并构建多馈入混合型的送端电网频率响应模型;然后基于系统闭环特征值分析其渗透率对送端电网的频率影响

制定相应的调频贡献度指标并建立优化方案

得出保证系统频率稳定性的最优配比;最后在Matlab/Simulink平台上对理论分析进行时域仿真

验证了该文分析的正确性。

Abstract

To quantitatively evaluate the frequency support performance of the transmission end power grid connected to the hybrid new energy station

the frequency characteristic transfer function is first used to tune the parameters of the frequency modulation unit of the single feed follow-up/grid construction new energy system

and a multi feed hybrid transmission end power grid frequency response model is constructed; Then

based on the closed-loop eigenvalues of the system

analyze the impact of its penetration rate on the frequency of the transmission end power grid

formulate corresponding frequency modulation contribution indicators

and establish optimization plans to obtain the optimal ratio that ensures the stability of the system frequency; Finally

time-domain simulations were conducted on the Matlab/Simulink platform to validate the correctness of the theoretical analysis presented in this paper.
