摘要: 电力用户参与电网侧互动用电和辅助服务已成为国内外关注热点,用户互动用电行为分析是其中一项核心工作。结合自组织映射SOM神经网络和K-means聚类算法,采用一种自组织中心K-means算法用于用户互动用电行为聚类分析,能够实现更加精准识别和快速聚类。首先,对自组织中心K-means算法原理进行分析,说明其与传统聚类算法相比在用电行为聚类分析中的优势;然后,构建峰谷分时电价背景下,基于用户心理学的调节潜力指标,并分析基于负荷数据和调节潜力指标的用户互动用电行为;最后,以某电力公司管辖区域用户的日常负荷数据为研究对象,将基于自组织中心K-means算法的聚类结果与其他传统聚类方法进行对比,证明基于调节潜力指标的自组织中心K-means算法在用户互动用电行为上的精准识别和准确聚类优势。

Abstract: The participation of power users in grid-side interactive power and auxiliary services has become a hot topic. Analysis of users interaction power behavior is a core task. Combining self-organizing map SOM neural network and K-means clustering algorithm, this paper uses a self-organizing center K-means algorithm for cluster analysis of users interaction electricity behavior and it can achieve more accurate recognition and fast clustering. Firstly, the principle of K-means algorithm in self-organizing center is analyzed, which shows its advantages in clustering analysis of electricity usage compared with traditional clustering algorithm. Then, under the background of peak-to-valley time-of-use electricity price, the adjustment potential index based on user psychology is constructed, and the cluster analysis of users electricity consumption behavior based on load data and adjustment potential index is analyzed. Finally, the daily load data of users in a jurisdiction of a power company is studied and the two-stage clustering results based on self-organizing center K-means algorithm are compared with the clustering results based on K-means algorithm, which proves the advantages of self-organizing center K-means algorithm based on adjustment potential index in the users accurate recognition and accurate clustering.

Key words:  user interaction, self-organizing center K-means algorithm, load data, adjustment potential indicator, clustering analysis
