摘 要：針對風電場出力隨機性、難預測性的特點建立了風電調峰容量需求模型，基于well-being分析原理，采用基于Kantorovich distance（KD）的forward場景削減技術選取典型風電出力場景對其隨機性建模。基于調峰容量需求模型，該報告提出了一種實用的含大型風電場的電力系統調峰運行特性分析方法，定量分析了風電場接入對系統調峰容量需求及運行特性等方面的影響。應用提出的模型對一個典型算例系統進行了接入風電后的調峰運行特性模擬計算及分析，結果證明該文所提方法，其計算結果精度較高，且大大降低了計算的復雜性，有利于系統規劃人員從整體上直觀、清晰地分析風電對系統調峰壓力及運行特性的影響，便于應用于工程實際。

關鍵詞：調峰運行特性 風電場 調峰容量需求 場景削減

Abstract：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.

Key Words：Peak load regulation operation characteristics； Wind farm； Peak load regulation capacity requirement； Scenario reduction
