Abstract: This paper focuses on the distributed voltage control problem of DC microgrids consisting of some different types of DC distributed generation (DG) units powered by wind and solar energies. A distributed voltage controller is developed for this DC microgrid to make all DG's voltages synchronise to a reference voltage. Meanwhile, the controller is designed by using a distributed PD idea, and based on multi-agent system (MAS) with external disturbances which is obtained by transforming the original microgrid model. Finally, the simulation results show the effectiveness of the proposed approach.

Keywords: DC microgrid; distributed voltage control; PD controller; disturbance rejection; model transformation; H_∞ almost; multi-agent systems; voltage tracking control.
