Operating modes of electric energy storage systems on the Moscow Central Ring

Improving the performance of electric traction systems is associated with the use of new technologies, the introduction of which is preceded by an assessment of the technical efficiency of their work. Nowadays, electric energy storage systems in Russia have not found application in electric traction systems, but questions are being actively developed on advisability and possibility of their use. And electric traction load of electric traction system of the Moscow Central Ring is not an exception, which forms in the conditions of domination on the area of passenger traffic and frequent electric tractions stops. Electric energy of high level of return of electric trains was formed on the site. Obtaining the technical result of assessing the use of energy storage systems of electric energy is most expedient to perform on the basis of simulation modeling of the interaction of electric rolling stock and electric traction system in the conditions of the Moscow Central Ring. Modeling results allow receiving the main characteristics of storage units and voltage load graph, determining the duration of work episodes in charge and discharge modes, their number and appropriate total volumes of electric energy per day. The received results allow assessing requirements to the technical characteristics of storage systems in relation to work conditions in the electric traction system of the Moscow Central Ring and performing assessment of economic efficiency of this activity
