摘要
随着城镇化进程发展与居民生活水平提升,城镇住宅能耗总量提升。与此相关,家用电器能耗占比增加。实际上,不同住户之间,住宅实际用能差异很大,分析其原因,住户的行为差异是巨大的实际能耗差异的重要原因之一。用能总量提升的背景下,需求侧响应尤为重要,要求对小时间步长的负荷特性有更加深入的研究。因此住宅逐时功率负荷特性,尤其是家用电器的逐时负荷特性备受关注,要求模型具备三个方面的特性:住户用能模式随机性,模型可推广性与验证的完备性。本文提出一种基于单户家庭单个家用电器能耗数据的分析方法与家用电器行为模型的构建思路,通过模型构建,实现家用电器能耗与逐时负荷特性的再现。本文以电视机作为研究案例,开展数据分析与模型构建,同时将提出的模型,与马尔科夫模型效果进行对比,经过模型检验,验证了提出模型的准确性与可靠性。文章所提出模型,对于单户住宅乃至区域住宅的用能分析,具有工程实际应用的可推广性。
With the development of urbanization and people＇s living standard, energy consumption of urban residential buildings has gradually increased, among which the energy consumption of household appliances account for a larger proportion. In engineering practice, energy consumption discrepancy exists in different households. One of the key factors is occupant behavior. With the development of power systems, demand side response and innovation technology concentrate on the load profile of the demand side, leading to the attachment of great importance to household load profiles and the accumulation fo corresponding researches. Therefore, the model is required to possess three characteristics, randomness with different usage patterns, generalizability and verifiability. The article proposes an analytical method based on the power data of single appliance in one household. After data analysis, one model establishment approach is proposed, hence the simulation of energy consumption and the load profile are realized. By taking television as an example, careful analysis and model establishment are carried out in the article, and the model is proved to be reliable. Also, a comparison of the model proposed with Markov model is made to further validate the simulation results. As for household energy consumption analysis from a single household to district households, the model is verified to embrace generalizability in engineering practice.
