Distributed generation(DG) mostly access to urban distribution network in form of micro-grid. This measure is conducive to energy saving and environmental protection, but increasing the difficulty of emergency management scheduling of the distribution network in case of emergency. This paper presented a optimal scheduling scheme for disaster-relief integrated resources considering operating characteristics of DG and importance of load in multi-microgrid: coordinately optimizing scheduling for DG, energy storage(ES), mobile emergency power(MEP). First, the model of importance of load was established. Then, coordinated optimizing model was presented, which taked the total power loss of the power-lossed load in distribution network and the operating cost of MEP as the objective function, to formulate the operating scheduling strategy for DG, ES, MEP, and was solved by the business software for linear programming. Finally, the superiority of this coordinated optimal scheduling was verified in the case study.
