论文摘要
为了提高电动分配系统的弹性，本文提出了一个随机的多周期混合组合线性编程模型，该模型决定了地下分配线路的位置以及如何协调移动发电机以在极端事件中服务关键负载。所提出的模型使用AC功率流程的线性化截距近似以及线路地下状态，开关的配置以及每个时间段内移动发生器的位置的二进制变量表示服务恢复过程。该模型还强制执行分销网络的径向配置，并考虑重新定位移动发电机所需的运输时间。使用IEEE 123-BUS测试系统的扩展版本，数值模拟表明，将地下分配线与移动发电机的部署结合功能可以显着提高电源对关键负载的弹性。
To improve the resilience of electric distribution systems, this paper proposes a stochastic multi-period mixed-integer linear programming model that determines where to underground distribution lines and how to coordinate mobile generators in order to serve critical loads during extreme events. The proposed model represents the service restoration process using the linearized DistFlow approximation of the AC power flow equations as well as binary variables for the undergrounding statuses of the lines, the configurations of switches, and the locations of mobile generators during each time period. The model also enforces a radial configuration of the distribution network and considers the transportation times needed to reposition the mobile generators. Using an extended version of the IEEE 123-bus test system, numerical simulations show that combining the ability to underground distribution lines with the deployment of mobile generators can significantly improve the resilience of the power supply to critical loads.
