Mobile energy storage systems(MESS),as emergency power sources,can play a significant role in restoring power to important loads during the post disaster recovery process.Considering that the nature of the occurrence of major power outages is due to the propagation of grid risks,a strategy for siting MESS configuration points in the framework of coupling distribution and transportation networks is proposed.Firstly,this paper describes the process of grid risk propagation with the help of SIR infectious disease model,and quantifies the risk propaga-tion ability and risk control ability of nodes;secondly,it proposes a multi-objective optimal siting model of MESS taking into account the risk control index of nodes,and solves the problem by using immune-optimization algorithm;finally,it constructs an urban distribution grid and its geographically corresponding urban transportation system,and carries out tests and comparative analysis to validate the proposed mobile emergency storage pre-disaster placement strategy.Finally,we constructed an urban distribution grid and its geographic counterpart urban transportation system,conducted tests and comparative analysis,and verified the effectiveness of the proposed pre-disaster location method for mobile emergency energy storage,and the results show that the effect of considering the impact of grid risk propagation is also not negligi-ble in improving the emergency response capability.
