Unpredictable occurrence of natural disasters in modern power systems has significantly increased the attentions to the outage management of multi-microgrid (MMG) systems. In this regard, a multi-objective two-stage outage management scheme is presented in this paper to protect undamaged microgrids (MGs) against load curtailment and minimize the curtailed loads simultaneously. Considering the importance of power system economic, this scheme is designed in a privacy-preserved transactive energy (TE) market and enables all MGs to participate in outage management voluntarily. In detail, a DC optimization is autonomously operated in the first stage in each MG to supply its demand loads. Then, the second stage is designed to exchange the surplus power of the last stage with the damaged MGs. These voluntary power transactions are pre-specified in contracts, adjusted between each MG and distributed system operator (DSO). Moreover, in this stage, the ADMM algorithm based on DC-OPF has prepared a privacy protection platform and proved the results' accuracy. The presented test grid is the IEEE 34-node test system and the numeric results demonstrate the effectiveness of the proposed multi-objective scheme.
