A power demand simulator of electric transportation systems for distribution utilities

Electric transportation systems have been one of the solutions to enhance the massive transport of passengers in large and medium size cities in developed countries. However, in some developing countries, such as Latin American countries, the electric transportation is just now searching has a solution for this problem. As a difference to the developed electric transportation systems, the introduction of electric transportation systems will be made in cities where the electric infrastructure of distribution utilities is completely developed. So, the distribution utilities of large cities without an electric transportation system require models and tools, in order to determine the electric load for the development of new massive electric transportation system in the area supplied by the utility. This paper presents a tool developed in Matlab useful to simulate urban trains systems, such as the computation of electric load as function of the type of transportation system; the train´s characteristics, way path characteristics, and passengers´ mobility, among other factors. The simulator estimates the electric load as function of time and computes the diversified load curves for each connection point (rectifier substations, for example) and connection point of the electric transportation system to the distribution system.
