MFRED 2019-2021 (public file, 15/15 aggregate version): 10 second interval real and reactive power in 390 US apartments of varying size and vintage, including Covid-19 pandemic-related changes in consumption patterns

10-second interval electricity data (real and reactive power) of 390 apartments located in >12 residential buildings in New York City (Jan 2019 - Dec 2021), published at level of 15 aggregated apartments per trace (\"15/15 rule\"). In line with stay-at-home and/or work-from-home patterns prompted by the pandemic, annual average load per apartment increased from 343 Watt in 2019 to 360 Watt in 2020, and then fell again to 347 Watt in 2021. This was accompanied by delayed load ramp-up during early morning hours, indicating changes in diurnal profiles, as well as an increase in phase angle, indicating higher portions of capacitive loads such as routers, computers, and other electronics. Files attached with this dataset cover 2020 and 2021 data. Data for 2019 as well as comprehensive explanations of the dataset can be found in Meinrenken et al. (doi.org/10.1038/s41597-020-00721-w), which is attached. Total number of files attached: 10.

本数据集涵盖纽约市12栋以上住宅建筑内390套公寓的10秒间隔电力数据（有功功率（real power）与无功功率（reactive power）），时间跨度为2019年1月至2021年12月，采用每15条聚合数据对应15套公寓的规则（即“15/15规则”）发布。受新冠疫情催生的居家隔离与居家办公模式影响，每套公寓的年平均用电负荷从2019年的343瓦特升至2020年的360瓦特，随后在2021年回落至347瓦特。与此同时，清晨时段的负荷爬坡出现延迟，反映出日负荷曲线的变化；此外相位角有所升高，表明路由器、计算机及其他电子设备这类容性负载的占比有所提升。本数据集的随附文件包含2020年与2021年的相关数据。2019年的数据集以及完整的数据集说明可参见Meinrenken等人的研究（doi.org/10.1038/s41597-020-00721-w），相关附件已随本数据集一并提供。本次附随文件总计10份。
