Specific Electrical Loads of Multi-Apartment Residential Buildings in the Agglomeration «Moscow - Moscow Region»

The selection of power for transformer substations and the cross-sections of electric wires with various voltages are based on the preliminary calculation of electrical loads. The experience of operating power supply systems in multi-apartment residential buildings in Moscow and the Moscow region demonstrates significant underutilization of transformers compared to their design electrical load. The reason for this lies in the inflated, obsolete normative values of specific electrical loads, which fail to consider the effects of energy-saving technologies in power engineering and household electrical appliances. Mass implementation of intelligent energy metering devices into urban electric grids allows for the development of new normative values for specific electrical loads, aligning them with actual values. The “Roselectromontazh” Association has conducted monitoring of electricity consumption in multi-apartment residential buildings within the Moscow agglomeration over the past two years, utilizing half-hour electricity load profiles. New reduced values for specific electrical loads have been substantiated, and the introduction of the category “urban agglomeration” has been proposed in normative documents, specifically applicable to metropolitan cities. A correlation has been identified between the maximum electricity consumption of groups of multi-apartment residential buildings and their maximum electrical load.
