摘　　要：极端自然灾害使配电网和交通网的物理结构同时遭受严重损害,进而引发交通道路受损拥堵以及配电网大面积停电事故,给电网恢复供电造成困难。但在现有交通网耦合配电网灾后抢修策略的制定中,仅以灾后初始时刻各交通道路的车流量和实际通行能力代表整个维修过程,忽略了交通道路车流量的时变性,以及因灾害导致无法抢修通行道路。为此,提出了考虑交通网和配电网耦合的灾后一体化故障恢复与抢修策略。首先,对地理和信息上相互依赖的交通网和配电网进行耦合,以保证抢修队路线计划的可行性和实用性;其次,通过求取各交通道路灾后初始时刻的权重值和故障抢修时间,对配电网故障线路进行聚类;最后,考虑抢修过程中交通网实际通行能力的变化,以配电网失负荷量最低为主要目标进行决策。并在IEEE 33节点配电网-32节点交通网节点系统上完成算例仿真,验证了所提抢修策略的合理性。Extreme natural disasters can cause serious damage to the physical structure of the distribution network and the transportation network at the same time,which in turn will cause damage and congestion of traffic roads and large-scale power outages in the distribution network,making it difficult for the power grid to restore power.However,in the formulation of the post-disaster repair strategy of the transportation network coupling distribution network,the traffic flow and actual traffic capacity of each traffic road at the initial moment after the disaster only represent the entire maintenance process,ignoring the time variation of the traffic flow of the traffic road and the emergency repair of the impassable road due to the disaster.Therefore,this paper proposes a post-disaster integrated fault recovery and emergency repair strategy considering the coupling of transportation network and distribution network.Firstly,the geographically and information-dependent transportation network and distribution network are coupled to ensure the feasibility and practicability of the route plan of the repair team.Secondly,by obtaining the weight value and fault repair time of each traffic road at the initial moment after the disaster,the fault lines of the distribution network were clustered.Finally,considering the changes in the actual traffic capacity of the transportation network during the emergency repair process,the strategy with the lowest load loss of the distribution network as the main goal is proposed.A simulation is completed on the IEEE33-node distribution network-32-node transportation network node system,which verifies the rationality of the proposed emergency repair strategy.
