Evaluation and Ranking of Electrical Transmission Reinforcement Options Using Machine Learning Techniques

电力网由三个基本要素组成：发电站、负荷中心和输电线路。输电线路连接发电站和负荷中心，电网的拓扑结构随着时间的推移而演变。从发电站到负荷中心新建输电线路是一个复杂的决策过程，涉及：（D1）满足可行性约束、政策和环境约束等;（D2）成本效益分析;（D3）潮流优化。在执行步骤D2和D3之前，电网运营商可能希望通过考虑D1来评估和排名新传输线的所有可能实例。在这个项目中，我们将开发一个框架来评估和排名的情况下，新的输电线路在给定的电网。对该框架的投入将是：（一）电网的拓扑结构;（二）电网所覆盖的物理空间的GPS（全球定位系统）注释地理图;（三）地理空间的重要特征，即城市、水体、山脉和禁区;以及（四）监管和环境限制。该框架的输出将是一个新的输电线路的潜在路线的排名列表。新传输线的每个实例将通过元组来描述：

An electrical power grid comprises of three basic elements: power generating stations, load centres, andtransmission lines. A transmission line connects a generating station with a load centre, and the topology of apower grid evolves over time. Drawing a new transmission line from a generating station to a load centre is acomplex decision process involving: (D1) satisfaction of feasibility constraints, policies, and environmentalconstraints, among others; (D2) cost-benefit analysis; and (D3) optimization of power flow. Before carrying outsteps D2 and D3, a grid operator may want to evaluate and rank all possible instances of a new transmissionline by considering D1. In this project, we will develop a framework to evaluate and rank the instances of anew transmission line in a given power grid. The inputs to the framework will be: (i) the topology of the powergrid; (ii) a GPS (Global Positioning System) annotated geographic map of the physical space covered by thegrid; (iii) important features of the geographic space, namely, cities, water bodies, mountains, and off-limitareas; and (iv) regulatory and environmental constraints. The output from the framework will be a ranked listof potential routes for a new transmission line. Each instance of a new transmission line will be described bymeans of a tuple:
