Abstract：Driven by the dual-carbon goals，to effectively reduce the carbon emissions of flexible DC

interconnected microgrids cluster and enhance the flexibility of system control，a low-carbon control strategy was

proposed. Firstly，a topology of flexible DC interconnected microgrids cluster was proposed，and the carbon

emission and low-carbon control characteristic of each distributed generator within the microgrids cluster were

analyzed. Secondly，two-level control objectives for microgrid and microgrids cluster were established，based on

which a hierarchical low-carbon control architecture was constructed. This architecture was divided into two parts：

the microgrid control layer and the microgrids cluster control layer，providing key references for the subsequent

design of the low-carbon control strategy. Then，based on the aforementioned architecture，a low-carbon control

strategy for microgrids cluster was proposed. In the microgrid control layer，by introducing the incremental carbon

emissions into the distributed control structure based on the consensus algorithm，the low-carbon control among

DGs within the microgrid and the restoration of bus frequency were achieved. In the microgrids cluster control

layer，by designing the control modes of interlinking converters，the microgrids cluster can conduct power

interaction with the DC distribution network in multiple forms，thereby meeting the diverse power supply demands

of the upper-level.Finally，simulation results verify the effectiveness and superiority of the proposed low-carbon

control strategy.
