Analysis of the Smart Grid concept for DC power supply systems

Abstract

The Smart Grid network system is a concept of a fully integrated, self-regulating and renewable power system with a network topology and includes all generating sources, main and distribution networks and all types of electrical energy consumers controlled by a single network of information and control devices and systems in real of time. The article proposes the introduction of the Smart Grid concept into the traction power supply systems, an analysis of the necessary steps to upgrade the traction substations, and the boundaries of the energy-saving effect from its implementation.
