| 摘 要： | 利用平均电价差值积分模型将电力市场中发电商的机组报价曲线转换为一维特征向量，从而采用传统聚类方法对机组报价曲线实现分类。通过对某电力市场的报价曲线聚类计算表明，在平均电价差值积分模型中使用20段分段模型，并采用离差平方和法进行聚类，可以对电力市场中机组的报价曲线实现较准确有效地分类。还可以采用量价指数CPI、HHI指数等方法对聚类结果进行进一步分析。

| Abstract: | An average electricity price difference-integration model is proposed in this paper.This model can transform unit's bidding curve of power producer in market into a one-dimensional feature vector,so it can implement classification of unit's bidding using classical clustering method.Through clustering calculation of bidding curve from certain electricity market,it is shown that bidding curve can be classified accurately and efficiently using 20-segment model and square sum of deviations in the average electricity price difference-integration model.Moreover,CPI (Capacity Price Index),HHI index can be used to analyze the bidding clustering results further. |
