A comparative analysis of the electric load on weekdays and weekends of multi-apartment buildings with electric stoves in the power supply systems of large cities

This article summarizes the typical daily loads of apartment buildings with electric stoves from various sources and the factors influencing power consumption. The initial data for the analysis were the results of automated measurements every 30 minutes for 3 years of commercial electricity metering installed in 7 apartment buildings using electric stoves in the Moscow region. The daily loads are presented for weekdays, Saturdays, and Sundays, and for winter and summer. The coefficients of unevenness, density, and shape are determined. The updated load graphs were compared with each other for different days of the week during different seasons, and with charts from the literature with different averaging intervals. It was found that the configuration of modern load curves for residential buildings differs significantly from those given in the literature in the minima and maxima, and in the duration of characteristic periods in the daily load.
