Today, the role of rail transportation in the world is of particular importance. The increase in the quality and speed of rail travel has enhanced the importance of high-speed and advanced trains; therefore, the study of high-speed rail and its feeding and controlling has been increasingly considered. At the beginning of the study, it is required to determine the type of high-speed grid power supply. DC's supply structure has surpassed other types of structures in recent years and has important advantages and benefits over AC power supply, which is addressed in this thesis. Of the benefits of DC power supplies can mention to the simpler connection of renewable sources to the grid utilizing modern technologies and advanced convertors. Also, with the increasing importance of renewable sources of energy, many projects have been utilized for the efficiency of these resources in the electrical railway, and parts of the stations’ energy consumption are provided by these sources. In order to use high-speed trains at intercity or urban districts, fields to exploit large-scale solar networks are provided. In this thesis, a 24-kv DC power supply grid, including two stations at a distance of 120 kilometers, is considered, that part of the grid’s power consumption is provided using a renewable source of solar power. Maximum Power Point Tracking (MPPT) has been used to maximize the power of solar panels. Stations, trains and variable resistances (due to the movement of the train) in the proposed model are single-ended, two-way, with braking energy and return to the network, and finally, with a photovoltaic renewable grid, and the DROOP control was used to control the station’s current and the voltage.
