提出了模拟住宅电力需求数据与英国家庭电力调查计量数据之间的比较研究。在本研究中，使用高分辨率概率模型来测试这种日益广泛使用的建模方法是否能够充分表示英国可用的最全面的计量电力需求数据集的统计特征。对经验和模拟用电量数据进行了汇总分析，特别关注平均日负荷曲线、家庭相对于年总需求的分布以及特定电器的年需求分布。使用定性和定量方法在模拟数据集和计量数据集之间进行了彻底的比较。家庭用电量和个人电器用电量的分布存在显着差异。获得了计量数据分布的参数估计，并给出了密度函数和累积分布的解析表达式。这些可以合并到新的和现有的建模框架中，并用作进一步分析的工具。
A comparative study between simulated residential electricity demand data and metered data from the UK Household Electricity Survey is presented. For this study, a high-resolution probabilistic model was used to test whether this increasingly widely used modelling approach provides an adequate representation of the statistical characteristics the most comprehensive dataset of metered electricity demand available in the UK. Both the empirical and simulated electricity consumption data have been analysed on an aggregated level, paying special attention to the mean daily load profiles, the distribution of households with respect to the total annual demands, and the distributions of the annual demands of particular appliances. A thorough comparison making use of both qualitative and quantitative methods was made between simulated datasets and it's metered counterparts. Significant discrepancies were found in the distribution of households with respect to both overall electricity consumption and consumption of individual appliances. Parametric estimates of the distributions of metered data were obtained, and the analytic expressions for both the density function and cumulative distribution are given. These can be incorporated into new and existent modelling frameworks, as well as used as tools for further analysis.
