Economic post-disaster restoration method of resilient distribution network based on mobile energy storage and electric vehicle V2G coordination
In recent years,the distribution network resilience enhancement technology developed in response to ex-treme events has developed rapidly.However,in practical applications,the high economic cost of technical solu-tions is one of the important factors restricting its implementation.Based on the above problems,this paper propo-ses an economic post-disaster restoration decision-making method for resilient distribution network with MESS and electric vehicle V2G,which reduces the economic cost of restoration while ensuring the restoration effect.In the pre-disaster stage,a pre-disaster electric vehicle scheduling model is established to obtain the distribution of elec-tric vehicles and the maximum output of each V2G station.According to the actual line layout and load informa-tion,the MESS temporary warehouse deployment location is determined.In the post-disaster stage,the comprehen-sive economic cost of post-disaster restoration is taken as the objective function to optimize the V2G station output and MESS scheduling in the restoration process.The proposed method is verified by multiple sets of examples.The simulation results show that the proposed collaborative restoration scheme can effectively improve the economy of the resilient strategy while reducing the post-disaster power loss of the system.
