摘要(Abstract)：
用户小微负荷资源众多、容量丰富、分布不均,可与电网进行双向互动。为打通电网公司与用户的精细化友好互动通道,实现用户侧小微负荷需求响应资源充分利用,构建了一种小微负荷智能监测与聚合分析系统。首先考虑用户功率、电流等特征差异,提出基于马氏距离相似度匹配的小微负荷构成非侵入式监测方法,实现小微负荷的细粒度监测;然后考虑小微负荷的物理特性和响应原理不同,提出基于用户舒适度指标的小微负荷需求响应能力分级聚合方法,实现小微负荷响应能力评估;最后,在某小微负荷智能监测与聚合分析系统中对所提方法进行实际测试,结果表明,该系统能较好地对小微负荷进行细粒度监测以及聚合分析与控制,可为后续更深层次研究提供测试平台。
Featuring multiple resources, rich capacity and uneven distribution, small and micro loads of users can interact with power grids bidirectionally. In order to get through the fine and friendly interaction channel between power grid enterprises and users and make full use of user-side small and micro load demand response resources, a smart monitoring and aggregate analysis system for small and micro load is constructed.Firstly, characteristic differences of power and current are considered, and a non-intrusive monitoring method based on Mahalanobis distance similarity matching is proposed to realize the fine-grained monitoring of small and micro loads; then, the different physical characteristics and response principles of small and micro load are considered, and a hierarchical aggregation method of small and micro load demand response capability based on user comfort index is proposed to realize the evaluation of small and micro load response capability;finally, the proposed method is tested in the small and micro load smart monitoring and aggregate analysis system. The results show that the system is superior in fine-grained monitoring and aggregate analysis and control over small and micro loads, which provides a test platform for further research.
