Abstract This paper presents a novel methodology for the Distribution Networks expansion planning based on Geographic Information Systems. The proposed methodology combines Delaunay Triangulation with a Mixed-Integer Linear Programming model in a 2-steps approach. Secondary substations are grouped in primary substation clusters, considering both normal and contingency operation. Topological and electrical constraints have to be fulfilled as well as a given level of reliability; the mathematical formulation includes feeder and substation constraints. The proposed methodology is expected to be only the first step of the whole network expansion planning. Hence, it has to be able to give macro information that planners can refine in the following steps of the planning process. A numerical case study on a real network illustrates the effectiveness of the proposed approach for the Distribution Network expansion planning problem.

基于GIS的正常和应急运行中考虑可靠性的高层配电网扩展规划方法

摘要 本文提出了一种基于地理信息系统的配电网扩容规划新方法。所提出的方法以两步法将 Delaunay 三角剖分与混合整数线性规划模型相结合。考虑到正常和应急运行，次级变电站被分组在初级变电站集群中。必须满足拓扑和电气约束以及给定的可靠性水平；数学公式包括馈线和变电站约束。预计所提出的方法只是整个网络扩展规划的第一步。因此，它必须能够提供规划人员可以在规划过程的以下步骤中细化的宏观信息。
