| Abstract |
This paper deals with the droop control of load sharing among multiple sources in DC microgrid. The DC Electrical Power Distribution System (EPDS) with parallel sources are under study in this paper. The voltage-fed and the current-fed paradigms are investigated including the cases when the cable impedance cannot be neglected. Global voltage feedback and local voltage feedback are discussed in terms of current-fed approach. The effect of different methods on the power sharing accuracy is presented. In addition, an enhanced voltage compensation method is proposed for both approaches. The analysis is validated by simulation studies. |
