Droop control has been widely applied in dc microgrids (MGs) due to its inherent modularity and ease of implementation. Among the different droop control methods that can be adopted in dc MGs, two options have been considered in this paper: I–V and V–I droop. I–V droop controls the dc current depending on the dc voltage while V–I droop regulates the dc voltage based on the output current. The paper...
This paper investigates the dynamic stability of a droop-controlled multi-generator system in the more electric aircraft (MEA). Based on the developed state-space model of the potential dc electrical power system (EPS) architecture, the stability boundaries of EPS operation depending on parameter variations including component parameters and operating conditions are investigated. The effect of multiple...
In presence of tightly regulated power electronic converters and motor drives in the more electric aircraft (MEA), stability is a great concern for the electrical power system (EPS) in the MEA. The DC electrical power distribution system (EPDS) of the MEA is one of the core architecture for electrical power transmission. DC transmission cables are also taken into account since it cannot be neglected...
Droop control methods are widely used in dc microgrids due to its simplicity and easy implementation. However, DC bus voltage deviation increases as the droop gain increases although accuracy of power sharing is improved. In order to overcome this paper proposes an improved voltage regulation method under high droop gain circumstance with consideration of cable impedance. It allows accurate power...
The paper deals with the stability of DC Electrical Power System (EPS) with paralleled sources for More Electric Aircraft (MEA). It is known that in presence of tightly controlled power-electronic driven loads the EPS bus capacitances and cable impedances have a significant effect on the system stability boundaries. The paper investigates these boundaries for one of the major paradigms for future...
