摘　　要：信息物理系统的深度融合为配电网动态、远程控制提供了技术支持。远动开关(RCS)可以在配电网遭受极端事件攻击后隔离故障,缩小故障区范围,参与网络重构恢复负荷。提出了RCS的鲁棒优化配置模型,在规划阶段完成配置RCS,以实现遭受极端事件后配电网失负荷损失最小化。基于防御-攻击-防御(DAD)框架,在第1层,规划人员确定RCS配置方案。针对规划后的系统,在第2层,攻击者寻找最严重的攻击方式。在第3层,运行人员考虑N-K的多重故障传播影响,通过RCS隔离故障并重构网络形成由分布式电源供电的微电网恢复负荷。3层相交互以提升配电网在最严重攻击方式下的负荷恢复效果。采用列约束生成算法求解模型,通过改进IEEE 37节点系统验证了模型的有效性。The deep fusion of cyber-physical system provides technical support for the dynamic and remote control of the distribution network.After extreme events attack the distribution network,remote-controlled switches(RCS)can isolate the faults,reduce the scope of the fault areas,and participate in the network reconfiguration to restore loads.The robust optimal model placement of RCS is proposed.The placement of RCS is completed in the planning stage to minimize the loss of load curtailment of the distribution network after extreme events.Based on the defender-attacker-defender(DAD)framework,the planner determines the plan of the placement of RCS at the first level.According to the system after planning,the attacker looks for the most serious mode of attacks at the second level.At the third level,the operator considers the impact of N-K multiple fault propagation,isolates fault through RCS and reconfigures the network to form microgrids powered by distributed generators(DG)to restore load.The three levels interact with each other to improve the load restoration effect of the distribution network in the most serious mode of attacks.The column-and-constraint generation algorithm is used to solve the model.The validity of the model is verified by the modified IEEE 37-bus system.
