面向弹性提升的智能配电网远动开关优化配置模型

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.
