Abstract：Under the promotion of carbon peak and carbon neutrality，in order to effectively reduce the carbon

emissions of distributed generators in islanded AC/DC hybrid microgrid clusters，a distributed low-carbon control

strategy was proposed. Firstly，the topology of the islanded AC/DC hybrid microgrid cluster was given. Based on

these，the low-carbon characteristics of the system were analyzed. Secondly，the distributed low-carbon control

strategy for an islanded AC/DC hybrid microgrid cluster was proposed. This strategy was divided into two parts：the

microgrid converters control layer and the interlinking converters（ICs）control layer. In the microgrid converters

control layer，this strategy taken the differential of carbon emissions from power sources as the incremental carbon

emissions，and introduced it into the secondary control term. It can ensure reasonable power allocation of the

generators according to the principle of equaling incremental carbon emissions，and achieve low-carbon control in

the microgrid level. In the interlinking converters control layer，this strategy introduced the deviation of incremental

carbon emissions between microgrids into the control structure of ICs and achieved low-carbon control in the

microgrid cluster level. Finally，the multi-condition simulation results show that compared with the conventional

methods，the proposed control strategy can realize low-carbon control of the system through collaborative control

between different levels.
