Quantitative Energy Efficiency Analysis Method for Power User Based on NILM Data

随着节能减排理念的普及,通过大数据技术分析用户用电情况,引导用户改善用电习惯、提高用电效率、降低用电成本已成为趋势。本文通过分析影响电力用户能效的因素,结合非侵入式负荷监测NILM(non-intru⁃sive load monitoring)技术可获得的数据,构建了易于获取和量化的家庭能效评估指标体系。在上述基础上提出了基于NILM数据的家庭电力用户能效量化分析方法,给出了能效量化分析和综合评估的具体流程,并提供了可构建的电力用户能效分析系统架构。最后,通过一些案例分析,验证了所提能效评估方法的有效性。

With the popularization of the concept of energy conservation and emission reduction,it has become a trend to analyze the electricity consumption of users through the big data technology,guide users to improve their electricity consumption habits,improve the efficiency of electricity consumption,and reduce the corresponding cost.In this pa⁃per,the factors affecting the energy efficiency of power users are analyzed,and an easily accessible and quantitative in⁃dex system for evaluating the household’s energy efficiency is constructed by combining the data obtained using the nonintrusive load monitoring(NILM)technology.On this basis,a quantitative analysis method for the energy efficiency of household power users is proposed based on the NILM data,and the specific process of quantitative analysis and com⁃prehensive evaluation of energy efficiency is given.In addition,the structure of the analysis system for the energy effi⁃ciency of power users is put forward.Finally,the effectiveness of the proposed energy efficiency evaluation method is verified through some case studies.
