“…A MEA EPS with a DC distribution network can also easier adopt parallel operation of multiple, dissimilar electrical energy sources [5]. The expected benefits of using parallel energy sources include reduction of the total weight of the main generators and convenient integration of energy storage devices (helping to level power demands hence further reduce generators ratings and weight), as well as improving the EPS availability [6]- [9].…”

The proposed approach, which can be used in terrestrial DC microgrids as well, effectively improves the load sharing accuracy under high droop gain circumstance with consideration of cable impedance. Since no extra communication line and controllers are required, it is easily implemented and also increases the system modularity and reliability. By using the proposed approach the DC transmission losses can be reduced and system stability is not deteriorated for normal and fault scenarios. In this paper optimal droop gain settings are investigated and the selection of individual droop gains as well as the proportional power sharing ratio has been described. Experimental results validate the effectiveness of the proposed method.Index Terms-DC power system, droop control, load sharing, voltage deviation, transmission losses.

“…However, the field current can be determined from the measurement of the current in the exciter. With this in mind, in a very easy way it can be concluded that there is a constant gain (profit) current which will assess the two excitation currents and it can be written as follows (13) This mathematical relationship describes the peak value of the AC generator excitation and represents a DC of generator rotor. In the analysis of power systems ASE (EPS, PES) of modern aircrafts you must take into account the variability of the mechanical turbine torque and the variability of environmental conditions in which the dynamic processes of components included in the onboard electrical network are implemented, hence the mathematical equations presented in discrete form.…”

Abstract. Based on the mathematical model of synchronous electric machine, basing on permanent magnets, presented in this paper, the key importance of alternator AC power sources in the form of generator (for conventional aircraft) and in the form of integrated unit starter/AC synchronous generator S/G AC (with respect to advanced aircraft concept in the field of more/all electric power MEA/AEA) was highlighted. In addition, through the analysis and selected simulations of the power supply system of a modern aircrafts, sources of onboard electrical energy (synchronous generator, integrated unit starter/AC generator) were located in board autonomic power system ASE (EPS, PES). Key components of this system are the electro-energetic power system EPS and the energo-electronic power system PES. Additionally, the analysis and exemplary simulations of key electricity sources based on mathematical models have contributed to highlighting the main practical applications in line with the trend of a more electric aircraft.

“…In this network, the output of the two generators is now rectified (using voltage source converters and phase angle control [18]), enabling easier paralleling of and power sharing between generators. Tuned droop profiles were employed within the converter interface controllers to ensure optimal power sharing between HP and LP driven generators, as illustrated in Figure 3 below.…”
