Abstract
Artikulu honek hidrogeno tren baten diseinu eta operazioa optimizatzeko algoritmo genetikoetan oinarritutakometodologia bat proposatzen du. Hain zuzen ere, metodologiaren bidez hidrogeno pilaren tamaina, bateriarentamaina, eta kudeaketa energetikoko estrategia optimizatzen dira, helburua trenaren bizitza-ziklo osoko kostuaminimizatzea izanik. Proposatutako metodologia balidatzeko benetako trenbide linea batean oinarritutako ikerketakasu bat aurkezten da. Optimizazioak itzulitako emaitza oinarrizko kasu batekin alderatzen da, trenaren kostutotala % 4,9 murrizten dela frogatuz. Lortutako emaitzek metodologiaren eraginkortasuna egiaztatzen dute.
This paper proposes an optimization methodology based on genetic algorithms for the design and operation of ahydrogen train. Indeed, the proposed approach optimizes the size of the hydrogen fuel cell, the size of the battery,and the energy management strategy. The aim of the optimization is to minimize the life cycle cost of the train. Inorder to validate the proposed methodology, a case study based on a real railway line is proposed. The results ofthe optimization are compared with a base case, what unveils that with the proposed methodology the total cost ofthe train can be reduced a 4.9%. The results validate the proposed methodology.
