Application of integrated linear programming models for the planning of distribution networks

This paper presents the development of a methodology to provide a technical and economical viability of some interventions aiming to improve planning electrical network task. For this goal, three linear mathematical models were developed: Capacitor placement, cable substitution and phase arrangement to optimize load distribution in the feeder. In order to evaluate voltage level, the models include a linear back-forward sweep power flow method. A heuristic solution based on Depth-first search (DFS) is used to integrate the models.
