Abstract
The majority of the ground vehicles operating on the airside parts of commercial airports are currently powered by diesel engines. These include vehicles such as apron buses, fuel trucks, and aircraft tractors. Hence, these vehicles contribute to the overall CO 2 emissions of the aviation transport system and thus negatively influence its environmental footprint. To reduce this damaging environmental impact, these vehicles could potentially be electrified with on-board batteries as their energy sources. However, the conductive charging of such vehicles via stationary cable connections is rather time-consuming. A dynamic wireless charging system to supply public transportation passenger buses with electric energy while in motion has recently been installed on the Korea Advanced Institute of Science and Technology (KAIST) campus and in the Korean city of Gumi. In this paper, we study configuration problems related to the use of this technology to make airport operations more environmentally sustainable. We concentrate on the power supply for apron buses and analyze the location planning problems related to the distribution of the required power supply and the wireless charging units in the apron road system. To this end, we develop a formal optimization model and discuss the first numerical results.
Highlights
Several types of ground vehicles operate on the airside parts of today’s commercial airports, on the apron
We assume that power supply units (PSUs) can be located next to nodes g1b, g5b, bd1, and bd2
From each of these locations, any link between the nodes in the set V C can be connected to and powered by the installed PSUs. We assume that those parts of the apron road network that are relatively close to terminal buildings and not in the center of the apron are natural candidates for the placement of the charging infrastructure for the apron buses
Summary
Several types of ground vehicles operate on the airside parts of today’s commercial airports, on the apron These include passenger-carrying apron buses, baggage and aircraft tractors, fuel trucks, and several others. This paper is structured as follows: in Section 2, we briefly describe important aspects of apron ground traffic at commercial airports and key aspects of dynamic wireless charging technology. On this basis, we specify our assumptions about the location problems that arise with the implementation of dynamic wireless charging technology for passenger-carrying apron buses at commercial airports and discuss the related literature.
