In this paper, a novel bipolar ±5 kV medium voltage direct current (MVDC) electric power system (EPS) having a distributed propulsion architecture is proposed to make the envisaged turboelectric NASA N3-X become all electric aircraft (AEA). Dimensions of the aircraft are estimated, and potential conductors for different cables connecting different buses are selected. Power flow (PF) analysis is done for the proposed EPS regarding selected conductors and calculated resistances, and results are discussed. To perform the PF analysis, since the target network is a DC network, a PF for DC power systems based on monotone mapping is developed and adapted to analyze the proposed all electric N3-X aircraft EPS. It is shown that the EPS proposed is reliable both in normal condition and all n-1 contingency situations, even when losing a busbar.
