Abstract
The purpose of the work is to evaluate the efficiency of promising electricity storage systems in the traction power supply system of the above-ground line of the Tashkent metro. The work uses methods of simulation modeling of the interaction of urban electric rolling stock and the traction power supply system with electricity storage devices. The modeling was carried out taking into account the frequency of changes in operating modes of electric rolling stock, including regenerative braking, which affects the energy performance of electricity storage systems. The characteristics of the operation of electricity storage systems, an assessment of the voltage level on the buses of sectioning posts, the duration of episodes of operation in charge and discharge modes, their number and the corresponding total volumes of electricity per day were obtained. The calculation results make it possible to assess the prospects for using electricity storage systems in the operating conditions of the ground part of the Tashkent metro.
