摘　　要：针对风电场出力随机性、难预测性的特点建立了风电调峰容量需求模型,基于well-being分析原理,采用基于Kantorovich Distance(KD)的forward场景削减技术选取典型风电出力场景对其随机性建模。基于调峰容量需求模型,提出了一种实用的含大型风电场的电力系统调峰运行特性分析方法,定量分析了风电场接入对系统调峰容量需求及运行特性等方面的影响。应用本文模型对一个典型算例系统进行了接入风电后的调峰运行特性模拟计算及分析,结果证明本文所提方法,其计算结果精度较高,且大大降低了计算的复杂性,有利于系统规划人员从整体上直观、清晰地分析风电对系统调峰压力及运行特性的影响,便于应用于工程实际。The variability and uncertainty of wind power output bring great difficulty to the quantitative analysis of the operation characteristics for peak load regulation of power system integrated with high penetration of wind power.For the random nature of wind power,the paper establishes a peak load regulation capacity requirement model for wind power.Based on the peak load regulation capacity requirement model for wind power,a methodology for analyzing peak load regulation operation characteristics of power system with a high penetration of wind power is proposed.The methodology makes it possible to quantitatively analyze the influences of wind power integration on the peak load regulation capacity requirement and operation indices.The case studies were carried out for a system,and the results verified the effectiveness and accuracy of the presented model.
