Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of the previous successful Special Issue "Electric Systems for Transportation". You can find the information and published papers of the previous Special Issue at
https://www.mdpi.com/journal/energies/special_issues/electric_transportation

The Guest Editor is inviting to submit papers for a Special Issue of Energies on the subject area of “Electric Systems for Transportation”. Transportation systems play a main role for the reduction of energy consumptions and environment impact all over the world. The big amount of energy of transport systems forces to adopt new solutions to ensure their performance with energy saving and reduced environmental impact. In these context technologies and materials, devices and systems, design methods and management techniques, related to the electrical power systems for transportation are continuously improving thanks to research activities. The main common challenge in all the application deals with the adoption of innovative solutions able to improve existing transportation systems in terms of efficiency and sustainability.

The special issue aims to collect papers dealing with analyses, models, simulations, experimental activities and project proposals on electric systems for transportation, achieving energy efficiency and environmental sustainability. We are pleasure to accept original research and review articles.

Topics of interest for publication include, but are not limited to:

  • Simulation tools and models of analysis for electric power systems for transportation
  • Design methods and management techniques for electric power systems for transportation
  • Measurement campaign and experimental study for electric power systems for transportation
  • New technologies, materials, devices and systems for electric power systems for transportation.

The aim of this study is to predict the electromagnetic interference (EMI) effect produced by a dynamic wireless power transfer (DWPT) system on a buried multiconductor signal cable. The short-track DWPT system architecture is here considered with an operating frequency of 85 kHz and maximum power transferred to an EV equal to 10 kW. The EMI source is the DWPT transmitting coil which is activated when a vehicle passes over it. The electric and magnetic fields in the earth produced by the DWPT coil currents are calculated numerically using the finite elements method (FEM). These fields are then used to derive the voltage and current sources that appear in the field-excited multiconductor transmission line (MTL) model, used for the buried shielded cable. The MTL is analyzed considering the first ten harmonics of the current. The currents and voltages at the terminal ends are calculated considering the wireless charging of a single electric vehicle (EV) first, and then the simultaneous charging of 10 EVs which absorb a total power of 100 kW. The preliminary results reveal possible EMI problems in underground cables. Full article

To enhance the current Public Transport (PT) service in the northern Italian region of Lombardy, this work tries to plan fully a new electric Skibus line connecting the cities of Santa Caterina and Livigno. As a first try outside the city environment, the electrification study is set on a limited mountain zone hence featured by steep grades and cold temperatures. In the first part of the paper, the energy consumed by an electric bus working in such a context is assessed, and from the learned outcomes, proper charging infrastructure is proposed. From the found results, the introduction of a new electric bus line in the chosen region seems feasible. Finally, in the last part of the work the performances of an electric bus fleet are compared with that of a diesel one, in terms of fuel costs and Well-to-Wheel (WTW) emissions. The results prove that an electric fleet would be more convenient for both the economic and the environmental aspects. Full article

The policies against climate change require the reduction of greenhouse gas emissions of marine transportation. To reach the planned goals, the most promising approach is working both on ships improvement and ports redesign. The latter must enable the new green ships supply with sustainable electrical energy, by integrating shore connection systems, local renewables, and energy storage systems. In this paper, a methodology to obtain such an objective is proposed, capable of taking into account both ships’ and ports’ characteristics. The methodology workflow is explained through a case study, where two shore connection power sizes and two different operative approaches for recharging the ship onboard energy storage are considered. A discussion about the most suitable energy storage technologies is also provided. The case study shows how the methodology can be applied, as well as demonstrating that the port infrastructure has a direct effect on the ship environmental performance. Full article
