Environmental concerns have driven the development of high efficiency and high-performance applications in the few years in the areas of renewable energy systems, electrical grids and green transportation. A large share of efforts has been put into the electrification of the aircraft, with the More Electric Aircraft concept, where the subsystems other than the propulsion have been substituted by their electrical counterparts. A further area of development is to increase the electrification of the airport itself, even in the view of future aircraft with increased energy storage requirements. The airport itself would become a grid-interactive microgrid with loads (utilities and airplanes) and renewable energy sources that can be installed on the buildings or on the lands adjacent to the runways, which normally does not allow for other kinds of constructions. Even in a post-COVID-19 world and with a possible reduction in the air transports, the focus on the efficiency improvement of the airports and aircraft will become of paramount importance to keep the travel affordable and the industry sustainable.

Title: Cascaded DC-DC Converter Systems: Stability Criteria and Solutions
Abstract: The distributed power system (DPS) has been used widely in such applications as space stations, aircraft, network servers, telecommunication power systems, and renewable energy generation system, thanks to its flexile system configuration, high-efficiency energy conversion, and high-density power delivery capability. Cascading converters is a typical connection style of the subsystems in DPS. This presentation will present the stability criteria and solutions for the cascaded dc-dc converter systems.

Title: Decentralized Dynamic Load Power Allocation Strategy for Fuel Cell/Supercapacitor-Based APU of Large More Electric Vehicles
Abstract: In this talk, an enhanced mixed droop control strategy will be presented for fuel cell/supercapacitor based auxiliary power unit (FC/SC-APU), which is usually used in large electric vehicles, to achieve the dynamic load power allocation in a decentralized way. By applying an adjustable virtual impedance droop scheme to the SC converter and a virtual resistor droop scheme to the FC converter, the SC is able to buffer the fast-changing or pulsating load power flow, leaving the FC only providing the average load power. Since the method is fully decentralized, it features high flexibility and scalability. Furthermore, the proposed strategy is very suitable for extending the system’s service life because the recovery and operational limit of the state-of-charge (SoC) of SC have been considered in the power allocation. The operational principle of the proposed control strategy and the system design will be elaborated, followed by which experiments are conducted to verify theoretical analyses.

Title: Efficient integration of renewable energy sources for green airports
Abstract: Massive integration of renewable energy sources (mainly low- and medium-power solar PV and wind power systems) is one of the key points to develop modern airports reducing the CO2 emissions. In this lecture, a brief overview of the methods to efficiently implement such energy sources will be addressed paying special attention to the advantages and drawbacks of modular power systems. This family of power converters is an attractive solution in terms of fault-tolerant capability with reduced cost but their use introduces collateral problems that need to be faced.
