Abstract:With the development of fully electric aircraft, especially the technological advances in hybrid-electric and electric propulsion aircraft, the optimization of aircraft power system design and operation has been effectively addressed. This paper analyzes the basic concepts and research progress of aircraft power system optimization, evaluation technologies, and dynamic management control methods. It summarizes engineering design trends for power system architecture optimization, based on multi-objective optimization that considers constraints such as weight, reliability, safety, efficiency, and renewable energy characteristics. Based on cost functions related to energy efficiency and power quality, this paper explores the relationships of power flow in the aircraft. Furthermore, it compares dynamic control strategies for different microgrid architectures in aircraft. With reference to relevant literature, this paper discusses power quality and stability issues in aircraft power systems. Finally, it discusses future energy interaction optimization between aircraft microgrids and electric propulsion aircraft power systems. This paper summarizes the development trends of optimization methods for aircraft power system architecture. Considering the current status of EMS technology development and architecture optimization, it discusses the energy optimization issues of future aircraft microgrids and aircraft power systems. Based on the latest technologies in aircraft power system energy management (EMS) and architecture, it proposes a control strategy that combines EMS and PHM (Energy Management System + Health Management System) in aircraft architecture selection.
