Almacenamiento de energía eléctrica mediante el frenado regenerativo para el sistema de transporte eléctrico masivo

Abstract

This paper proposes a mathematical model for the design of the storage system. This system is for the energy that is recovered in a huge vehicle. The vehicle is employed on context of an electric massive transportation as a subway. In order to accomplish the task with supercapacitors, some aspects are taken into account. The physical variables that affect directly the electrical energy consumption and recovery. The energy profile is obtained through successive georeferenced simulations on SUMO. The software allows to get the power that is required on every moment of the simulated journey. This data is employed as input for the model of storage elements on Simulink. Then, the authors propose a strategy to establish the quantity of energy that is available on different type of scenarios that are established on this paper. The changes modify the way electric regenerative braking is employed. Some aspects that the authors take account include the passengers demand, acceleration, deceleration and speed of a subway. The regenerative braking and supercapacitors main characteristics are also approached. The results of math modelling include to get the voltage on the storage system during all the journey of the subway.
