Improved Energy Management of Capacitive Energy Storage in Metro Railcar by Simulation

Abstract

This paper focuses on the use of modeling

and simulation of a renewable energy. The capacitive

energy storages contribute to the rapid energy recovery

associated with regenerative braking in electric vehicles.

This power system allows the acceleration and

deceleration of the vehicle with a lower loss of energy.

Short-distance passenger traffic on electrified lines is a

domain where brake energy recuperation might reduce

the total energy consumption significantly. In this paper

the results of simulation models by Matlab-Simulink for

an urban-metro railcar and some methods for reducing

the needed value of capacitance by an improved energy

management are presented. The aim of the new

management of the energy storage system for decreasing

the needed value of capacitance and improving the

system performance is presented.
