线路加固与储能车协同配置的韧性提升两阶段鲁棒优化方法OA

To defend against extreme disasters and enhance the resilience of distribution networks,a coordinated config⁃uration method of line reinforcement and mobile energy storage vehicles(MESVs)is proposed.First,a two-stage robust optimization model considering uncertain fault scenarios is established.The framework consists of an investment stage in which the line reinforcement and MESV configuration are optimized and a recovery stage in which the MESVs and other power sources are dynamically dispatched under the worst-case fault scenario.The objective function minimizes the sum of investment cost and load shedding loss,and the decisions on line reinforcement and configuration of MESVs are optimized under conditions including device quantity limits,network operation constraints,MESV operation con⁃straints and radial topology requirements of the distribution network.Second,a nested column-and-constraint genera⁃tion algorithm is adopted to solve the model,and a heuristic initialization strategy is introduced to improve the algo⁃rithm's convergence efficiency.Simulation results show that the coordinated configuration can ensure that the recovery ratio of critical loads exceeds90%under the worst-case fault scenario.Compared with the single configuration scheme,the proposed method not only reduces load shedding loss in the distribution network,but also improves the economic performance.This method can be extended to the coordinated configuration of additional devices,as well as the optimi⁃zation of pre-disaster investment and post-disaster recovery schemes,thereby effectively enhancing the resilience of dis⁃tribution networks.
