Distributed Power Allocation and Scheduling for Electrical Power System in More Electric Aircraft

Several major technical obstacles appear when moving toward more electric aircraft (MEA) architecture. First, there has been an increasing number of power electronic components used in aircraft power systems, leading to the modelling complexity. Second, the number of variables for system modelling increase significantly, leading to high computational complexity. To overcome these difficulties, this report proposes (1) a mathematical model of hybrid AC/DC electrical power systems for MEA architecture; and (2) a distributed power allocation and scheduling strategy based on the Lagrangian relaxation to reduce the computational complexity. Simulation results show that the distributed optimization approach is able to achieve good performance whilst reducing the computation complexity when the scale of an electrical power system increases.
