Impact of Electrification in the Road Transport Sector on the Level of Electricity Consumption and Daily Load Curve in the UES of Russia

The article assesses the impact of potential motor transport sector electrification on the value of the aggregate demand for electricity and capacity in the UES of Russia. Despite official documents suppose quite modest quantitative targets for the electric transport until 2030, in the longer term, a large-scale replacement of oil fuel with electricity will have a significant effect on reducing greenhouse gas emissions, but will also require a more intensive development of generating and network capacities in the electric power industry. The scenaric forecast for the development of electric transport is made with the allocation of three segments - cars, trucks and buses, which allows taking into account the characteristics of electricity consumption characteristic of each of them. Another important result is an assessment of the possible extent of the influence of electric transport on the configuration of a typical daily load curve. The paper considers various modes of using infrastructure for electric transport charging, which result in different daily load curves. It is shown that, depending on the scales of electric transport development, their annual electricity consumption in the country will lay in the diapason from 168 to 460 TWh. At the same time, depending on the charging mode of electric vehicles, the additional power demand will vary from 26 to 74 million kW, and the amplitude of fluctuations in the hourly loads of electric vehicles will vary from two to four times.
