摘要
传统的负荷曲线描述方法难以全面描述负荷变化特征。文章尝试采用用户画像技术进行居民负荷多尺度立体化的用电特性研究。首先,基于大数据平台中的可用数据资源,建立了表征居民负荷用电特性的标签体系。为了快速高效地获取各类典型用户特征,应用标签体系,在大数据平台支撑下,应用分布式聚类算法对海量居民用户用电数据进行聚类分析。最后,针对每类用户,文章绘制了四季的典型日和典型月负荷曲线以及年持续负荷曲线并进行了对比,同时分析了每类用户的负荷波动率和需求响应水平,以构建包含用户的用电时序规律和用电弹性特征的变时间尺度用户画像。分析结果能够可视化地描述居民负荷的时间分布特性及用户用电特性,可为合理制定电价套餐及优化用电模式提供参考。
Traditional load curve description methods are difficult to fully describe the characteristics of load changes.Therefore, this paper attempts to use user portrait to study the multi-scale high-dimensional electrical characteristics of residential load. Firstly, based on the available data resources in the big data platform, a label system is established to characterize the electricity consumption characteristics of residential loads. In order to quickly and efficiently acquire all kinds of typical user characteristics, a distributed clustering algorithm is applied to cluster and analyze massive residential users' electricity data based on the label system and the support of big data platform. Finally, the typical daily and monthly load curves of four seasons and annual continuous load curves are drawn and compared for each type of representative users. At the same time, the load fluctuation rate and demand response level of each type of users are analyzed to construct a variable time scale user portrait including users' electricity timing law and electroelastic characteristics. The analysis results of this paper can visually describe the distribution characteristics of residential load and the electricity consumption characteristics of users, which can provide a reference for the rational formulation of electricity price and the adjustment of electricity consumption patterns.
