Transportation Goes Electric – Exploring the Potential of Smart Charging Strategies for Airports
- 2023

Konferensbidrag (refereegranskat)abstract
- Transport electrification continuously increases globally and propagates to new, even-larger vehicle applications due to decreased costs, battery technology improvements, and charging infrastructure rollout. This work highlights the importance of strategic planning for large electric vehicle charging nodes, like depots, terminals, airports and ports. Specifically from the perspective of predicting future power requirements and how to satisfy energy demand using a combination of smart charging algorithms, local photovoltaic electricity production and battery energy storage systems. A case study is presented where developed tools and models are applied to an airport for high-power charging of future electric aircraft.

Tidskriftsartikel (refereegranskat)abstract
- Following the societal electrification trend, airports face an inevitable transition of increased electric demand,driven by electric vehicles (EVs) and the potential rise of electric aviation (EA). For aviation, short-haul flightsare first in line for fuel exchange to electrified transportation. This work studies the airport of Visby, Sweden and the effect on the electrical power system from EA and EV charging. It uses the measured airport loaddemand from one year’s operation and simulated EA and EV charging profiles. Solar photovoltaic (PV) and electrical battery energy storage systems (BESS) are modelled to analyse the potential techno-economical gains.The BESS charge and discharge control are modelled in four ways, including a novel multi-objective (MO) dispatch to combine self-consumption (SC) enhancement and peak power shaving. Each model scenario iscompared for peak power shaving ability, SC rate and pay-back-period (PBP). The BESS controls are alsoevaluated for annual degradation and associated cost. The results show that the novel MO dispatch performswell for peak shaving and SC, effectively reducing the BESS’s idle periods. The MO dispatch also results in the battery controls’ lowest PBP (6.9 years) using the nominal economic parameters. Furthermore, a sensitivityanalysis for the PBP shows that the peak power tariff significantly influences the PBP for BESS investment.
