Dynamic Time and Frequency Domain Modeling of Aircraft Power System with Electrical Accumulator Units (EAU)

The movement to more-electric architectures in airborne systems has drastically altered the dynamics of power flow in the EPS with the addition of numerous high-power electric loads and has increased the complexity of designing the electrical power system (EPS). Such high-power dynamic loads may cause undesirable system performance from both a dynamic-transient and a spectral-content (frequency-domain) perspective. In order to mitigate such undesirable performance, modern EPS designers must develop and apply suitable mitigation strategies, which typically involve energy storage, filtration, and/or advanced control. However, limited tools exist for the quantification of a proposed solutions impact on power quality at the integrated-system level from the dynamic-transient and frequency-domain perspective.
