Economical Efficiency of Energy Storage for the Traction Energy System

Abstract

The paper provides results of the study dedicated to estimation of the energy storage economical efficiency in the traction energy system of electric railways. The energy storage offered will allow obtaining the line of technological and technical advantages: increasing the degree of recuperation use, which will lead to reduction of consumed traction energy, obtained from the external power system; minimizing risks, in the part of failures in energy supply of the infrastructure complex facilities; increasing economical efficiency indicators; optimizing costs in traction energy supply; equipping energy supply facilities with efficient technical means and technological systems. Statement of need of the products designed is provided. The definition of economic effect from using the developed products on the railway network of JSC “Russian Railways” and the compensation period, and the project risk analysis have been given.
