Mobile Energy Storage Scheduling for AC-DC Microgrids Enabling Low-carbon Airport

Airport energy efficiency has attracted increasing attention in decades as it plays important role in global carbon footprint due to the huge assumption of aviation diesel in daily operation. Auxiliary power unit (APU), providing necessary power to aircraft for ground service, is particularly a high-emission and less cost-effective way during the turnaround process. In this paper, the mobile energy storage system (MESS) is applied for reducing APU usage by switching power supply. Firstly, the design of MESS with lithium-ion batteries packs and power conversion system are introduced. Then, considering operation mode of MESS and time-of-use pricing policy, an MESS scheduling model with deterministic flights plan for AC-DC hybrid microgrids is proposed to maximize the economic and environment benefit of airport operator. At last, the numerical results on a simplified airport test system verify the effectiveness of the proposed model, and the practical benefit analysis in an actual airport validates the application potential of MESS.
