Control?Based Stabilization of DC Microgrid for More Electric Aircraft
摘要
Abstract
Electrifying the on-board subsystems of aircraft becomes an inevitable process as being faced with the environmental pollution,along with the proposed concept called more electric aircraft(MEA). With the increasing number of on-board power electronic based devices,the distribution system of the aircraft can be regarded as an on-board microgrid. As it is known that the load power electronic converters can exhibit constant power load(CPL) characteristics and reduce the system stability,it is necessary to accurately predict and enhance the system stability in designing process. This paper firstly analyzes the stability of an on-board DC microgrid with the presence of CPL. Then,discusses the reasons behind instability and proposes a control strategy to enhance system stability. Finally,the simulation results are worked out to validate the analysis and the effect of the proposed control strategy.关键词
