Ubicación óptima de generación distribuida en redes de distribución usando programación no lineal entera mixta

Abstract

The main objective of this investigation is to determine the finest location of distributed generation in an electrical distribution system at a main feeders’ level through the resolution of a mixed integer non-linear programming model, which is resolve by means of the GAMS computational tool. The mixed integer nonlinear mathematical programming model will be applied to a 33-bar IEEE distribution system, which will determine the optimal location of the GD. In order to do this, the inherent characteristics to perform the operation of electrical systems will be consider into play. In this scenario, a comparative analysis will be perform with a commercial software for the simulation of electrical systems – ETAP. This system will allow simulating the IEEE system and calculate the results of the proposed mathematical model. Once the mathematical model is evaluated, four study cases will be generated, in which different amounts of GD are integrated. In these cases, technical variables are calculate it, such as voltage level, losses, among other significant aspects. These will allow us to conclude that the mixed integer non-linear programming model makes it possible to find the optimal location of several GD units in the network, guaranteeing the technical conditions of the network and fulfilling the objective of minimizing losses in the system.
