IEEE VTS Motor Vehicles Challenge 2019 - Energy Management of a Dual-Mode Locomotive

Energy management strategy to optimise regenerative braking in a hybrid dual‐mode locomotive

“…The proposed EMS is evaluated by simulations using the dualmode locomotive model, and speed and bus power profiles provided by the IEEE VTS Motor Vehicles Challenge 2019 organisers [1]. The problem constraints are presented in Table 1.…”

“…Following the rules and the IEEE VTS Motor Vehicles Challenge's philosophy, the three profiles presented in [1] are used to tune the EMS. This tuning is performed following the methodology presented in Section 2.10.…”

“…The viable solutions are evaluated and compared using a multi‐objective function composed of six cost functions to minimise [1] (i) The hydrogen consumption . It depends on the mass flow, which at its time depends on the current supplied by the FC with the hydrogen mass flow (g/s) and the hydrogen cost per unit of hydrogen mass . (ii) The FC degradation .…”

“…A braking resistor is implemented in the locomotive. It is modelled as a perfectly controllable current source [1]. The braking resistor use must be minimised.…”

Modelo de operador fraccional para describir la dinámica de lossupercondensadores

“…Los supercondensadores (SC) han tomado gran importancia en los últimos años. Dada su gran densidad de potencia y eficiencia en el almacenamiento y entrega de energía, se utilizan en aplicaciones tan diversas como, por ejemplo, la integración de energías renovables en las redes eléctricas [1,2,3], frenado regenerativo en vehículos híbridos [4], fuente de potencia en locomotoras eléctricas híbridas [5] y fuentes de suministro ininterrumpido de potencia UPS [6]. Aparte de sus aplicaciones, existe el interés de desarrollar modelos matemáticos con el propósito de describir su dinámica utilizando variables de operación V-I [7,8].…”
