摘要：
The construction of an efficient, low consumption, reliable DC distribution system is an important way to achieve flexible access and efficient matching of DC power and DC load, which has greater development potential compared with AC distribution system. This paper described the system composition, voltage level selection principle and topology structure of DC power distribution at first. Secondly, this paper proposed a flat and easy-to-expand power management and coordinated control method under different operation modes for muti-power converters based on voltage information coding, which can meet the needs of DC system fast response control. Finally, key parameters were set by establishing a system small signal stability model to ensure system stable in small disturbance. The simulation results verify the effectiveness of the proposed power management and control strategy. © 2020 Chin. Soc. for Elec. Eng.
