摘要

风电对电力系统现有调频体系的影响是否显著历来存在争议。文中考虑常规电源、负荷等与风电频率特性的交互作用

推导了含不同比例风电的系统总功率波动概率模型

进而得到最大频率偏差、静态频率偏差、一／二次调频调整速度、调频备用需求等关键调频指标随置信区间变化的概率表达式

从而提供了定量分析风电对系统调频体系影响的方法。对某省电网进行仿真分析提供了参考性结论。

Abstract

There have all along been two opposite opinions on the impact on power system frequency regulation from wind power. To improve the current research

the mutual behavior of conventional units and load is taken into account in focusing on quantitative analysis of the impact on multi time scale frequency regulation from high proportion wind power. The probabilistic combined power fluctuation model of power system with different ratios of wind power is derived prior to finding out the function with given confidence interval of those key indices used to estimate frequency control performance

including the maximum frequency control error

static frequency control error

primary/secondary frequency control speed

and reserve. Accordingly

a method for analyzing the impact of wind power on power system frequency regulation is proposed

providing a provincial grid with useful advice by simulation.
