A planning model for siting, sizing and timing of distribution substations and defining the associated service area

Abstract A new planning model is developed for solving sizing, sitting and timing of distribution substation and defining the associated service area. The model incorporates a non-discrete function that accurately simulates the different cost components of distribution substations. Voltage, capacity, power conservation and radial-flow constraints are included into the developed model. The efficiency of the developed model is illustrated using a detailed numerical example.
