Techno-economical analysis of DC railway traction networks: a methodology to optimally selected the system contracted power

Abstract

In the present work, a real traction system operated under different scenarios and using different technologies is analysed. The analysis of the technical simulations providing electrical variables will be conjugated with optimization methods applied to the economic study of the network operation in order to extract the different factors that a higher correlation in the electrical variables as well as the operation cost. In particular, the work is focused on establishing a general method that allows the railway operator to properly select the electric tariffs and its corresponding contracted capacity optimally so that the electricity bill is minimized. To do so, a previous implementation of a tool that calculates the electricity bill has been done.
