Abstract: The transition to more-electric/all-electric aircraft represents an inevitable trend in aviation development. Onboard power system exhibits the characteristics of an islanded microgrid with high penetration of power electronics. This talk will introduce typical onboard power system architectures and hierarchical control for future more-electric/all-electric aircraft. In primary control, enhanced droop control strategies will be discussed, enabling precise power distribution among multiple generation channels and rapid dynamic response. Secondary control employs system-level distributed control approaches to minimize bus voltage deviations, enhancing both the voltage quality of buses and the accuracy of power sharing among parallel sources. Finally, the talk will present stability analysis of the onboard MEA power system based on hierarchical impedance participation factors.
