Transformer procurement and relocation at a large electric utility: a mixed 0-1 linear programming model

The Power Delivery Substation Division at Florida Power and Light (FPL) must plan and provide logistical support for about two thousand transformers located at roughly four hundred substations. Each year, to meet new transformer requirements, the Division must make the decisions of procuring and/or relocating transformers. Due to the large number of transformers and substations involved, there is a strong need for a systematic approach to determine optimally the decisions for transformer procurement and relocation, as well as their schedules. In this paper, a mixed 0-1 linear programming model is developed for that purpose.<
