Investigation on the Selection of Electric Power System Architecture for Future More Electric Aircraft

This paper identifies the most promising electric power system (EPS) architecture for a future more electric aircraft based on reviews and evaluations of both system weight and stability feature of the existing EPS architectures. When comparing the overall system weight of different architectures, various aspects, including voltage generation, wiring system, ground operation, power conversion, and complexity of integrating alternative energy sources, are considered. After choosing the possible candidates among all the possible architectures by using weight-saving criterion, stability features for the initially selected candidates are further evaluated. Necessary simulation studies are carried out in MATLAB/Simulink to prove the correctness of stability study. Finally, the one both good at weight saving and with the highest stability region is deemed as the most promising EPS architecture for future MEAs.
