面向“削峰填谷”的电力客户用电行为分析

为对海量电力客户实施有针对性的“削峰填谷”措施,提出了一种面向“削峰填谷”的海量电力客户用电行为分析方法.首先,利用聚类算法对国网某省公司主网一年的日负荷曲线数据进行聚类分析,得到不同时期主网的负荷特征.然后,分别对每个时期下所有电力客户的日负荷曲线数据进行聚类分析,得到不同主网特征下用户群体的负荷特征,对比主网和用户的负荷特征得到用户群体的“削峰填谷”模式.最后,利用动态时间规整算法将未来日期与历史日期进行匹配,得到未来日期用户群体的“削峰填谷”模式.实证研究表明,分析结果可以为有序用电、峰谷电价等公司决策提供更有针对性的参考依据,以更进一步实现配电网负荷的“削峰填谷”和平稳运行.

Analysis of customers' electricity consumption behavior for peak load shifting

In order to implement well-directed peak load shifting for massive customers,a method for analyzing massive customers' electricity consumption behavior for peak load shifting was proposed.Firstly,clustering algorithm was used to cluster daily load curves of the main power grid in the previous year and get load characteristics in different dates.Then the load curves of all customers under every date cluster were clustered,the peak load shifting method was derived by comparing the load characteristics of the main power grid and customers.Finally,the peak load shifting method in a future day was given by date matching between the future day with a historical day using dynamic time warping (DTW).Empirical study shows that the method is conductive to peak-valley electricity pricing and orderly electricity consumption and can further achieve peak load shifting and stable operation of the main power grid.
