Abstract: Voltage and current balance plays an important role in ensuring the normal operation of DC microgrid.

Therefore，a new distributed voltage and current control method was proposed to realize the current sharing

and voltage sharing regulation of DC micro-grid. The considered DC micro-grid was composed of several distributed

generation units（DGU）interconnected by resistive transmission lines. A general energy source was contained in

each DGU and load current was provided through DC-DC Buck converter. The proposed distributed control scheme

was independent of the initial conditions of the controlled micro-grid，and current sharing and average voltage

regulation were realized. In addition，the proposed scheme only needs to measure the current generated by the grid，and is independent of the parameters of the micro-grid and the topology of the communication network. Finally，the simulation experiment was carried out to verify the proposed scheme. Simulation results show that the proposed algorithm has good global convergence. The research results can provide reference for DC micro-grid control.
