The Smart Grid network system is a concept of a fully integrated, self-regulating and renewable electric power system, which has a network topology and includes all generating sources, trunk and distribution networks and all types of electric energy consumers, managed by a single network of information and control devices and systems in real time mode. The article proposes the introduction of the Smart Grid concept into the traction power supply system of railways. The functional properties and technical solutions that will allow implementing the principles of Smart Grid intelligent power supply systems are considered. A comparative description of the functional properties of the existing energy system and the energy system based on the Smart Grid concept is presented. Possibilities of introducing Smart Grid into the traction power supply system of direct current due to increasing the carrying capacity of trunk networks, consumption management, location of distributed energy sources in distribution networks and closer to consumers have been determined. The limits of the energy-saving effect from the introduction of the Smart Grid concept into the traction power supply system have been determined.
