Abstract : Today, the supply of electric power stations in the country is carried out using the national electricity grid and diesel generator as emergency power, which is related to the costs related to the construction of 20 kV lines and repair and Their maintenance will be substantial. Considering the fact that Iran has high potential for using ultraviolet and diffusive manufacturing systems in the field of solar radiation, and more than 250 railway stations in the central regions of Iran with high solar radiation (4.5-5.4 kWh / m2day). Therefore, due to the increase in the price of energy carriers and network equipment, the technical and economic appraisal of the use of photovoltaic-based distributed generation technology at the stations to supply the entire station, or part of it, as an approach to Becoming a consumer to a producer is essential. In this paper, with the help of simulation in the Gom and Homer program environment, an economic assessment for the replacement of renewable energy in the power supply of the railroad station in a composite state including sources such as photovoltaic systems along with diesel, wind generators and batteries for one The station is based on real costs and the results of this method are compared with the state of the network construction and purchase of electricity. The approach of this paper is helpful in deciding on the type and amount of each renewable resource at different stations based on the country's energy atlas.
