Research on Network Configuration and Voltage Control of DC Distribution Station

With the rapid development of distributed energy, the power grid, especially the urban power grid, is facing many challenges. In this paper, the concept of DC distribution station is proposed. As a key component of DC distribution system, DC distribution station will play the advantages of DC distribution technology to promote the transformation of traditional urban power grid into a new urban power grid. A reasonable overall topology is proposed, and the appropriate voltage control strategy is selected. Besides, the simulation model of DC distribution station is built in MATLAB/SIMULINK. The simulation under steady-state condition verifies the feasibility of the DC distribution station and the correctness of the control strategy.
