Abstract: Advantages of DC distribution networks in the aspects of distributed generation consumption, DC load access, and network structure upgrade have been widely recognized. However, some new unstable factors are introduced while reducing converting stages and simplifying control objective. This paper performs an extensive review on DC distribution network structure and its characteristics. Then typical operation characteristics and stability problems of DC distribution network are analyzed. Then, several typical control methods and their application scenarios of DC distribution systems are summarized and discussed. The future research challenges, form the authors point of view, are also provided in the final concluding part.

Key words: DC distribution system, characteristics analysis, virtual inertia control, virtual impedance control
