SHC seminar: Super-cap based hybrid energy storage system for electric urban rail transport systems
Swedish Electric and Hybrid Vehicle Centre (SHC) is happy to invite you to a seminar with prof. Mohammad Reza Zolghadr, Sharif University of Technology, Tehran, Iran
WHEN: 13 September 2016, at 10.30-11.30
WHERE: Room Fredrik Lamm, Hörsalsvägen 11, Chalmers University of Technology, Göteborg
REGISTRATION: By this link at the latest 12 September. Participation is free of charge
ABSTRACT: In the urban railway transportation system, large amount of power is consumed for starting the movement and acceleration of the train. A great part of this energy is transformed to the train kinetic energy which in the case of break is reduced to zero. Thus recovering train kinetic energy during the brake reduces train energy consumption. One of the possible ways is using energy storage during the brake and using it again during acceleration. In this presentation, using super capacitors as fixed and mobile storage for regenerative brake of electric urban trains is investigated. A MATLAB based simulation tool is developed to analyze the electric power transfer in the subway electric grid. Part of line 1Tehran subway is simulated for 5 different traffic scenarios. Energy consumption and voltage level in different points is compared in railway transportation system equipped with different storages with each other and also with subway system without storage system. PSO and Genetic algorithm are used to find the optimal values for the capacity of fixed and mobile parts of the super-cap based storage system.
