Analysis of the maximum electrical load of multi-apartment residential buildings in the power supply systems of cities

This article presents the results of the analysis of the power consumption of apartment buildings with electric stoves (in Moscow). The initial data for the analysis is the power consumption by years of several multi-apartment residential buildings, recorded by electric meters on the incoming switchgear of the buildings under consideration every thirty minutes. The dynamics of changes in the maximum electrical load is considered in the context of the year taking into account the air temperature, time of day and day of the week. The time intervals have been established when the absolute annual maximum power consumption of residential buildings is observed: month, day of the week, day, time of maximum electrical load. In conclusion, a comparison is made of the actual maximum electrical load of apartments in the buildings under consideration with the electrical unit loads of apartments presented in the current standards used in the design of urban power supply systems.
