Ubicación y Dimensionamiento Óptimo de Generación Distribuida en Redes de Distribución Usando Pso

This article presents the location and optimal sizing of distributed generation with active power injection in radial distribution systems through optimal power flow through the particle swarm optimization (PSO) algorithm. The criteria proposed as objectives are to minimize power losses in the lines and improve the voltage profile by reducing deviations from the nominal value. Compliance with these criteria is also defined as an objective function variable, considering the minimization of costs associated with distributed generation. The proposed restrictions are subject to the power balance, the permissible voltage margins and the power injection limits of distributed generation. The analysis was carried out in the IEEE 15-bar and IEEE 33-bar radial distribution systems as case studies, and the implementation was developed in the MATLAB mathematical software environment. The methodology used (PSO) also allowed to improve the indices of quality conditions, such as the average voltage deviation and the maximum voltage deviation. The results obtained show that the method used for the location and optimal sizing of distributed generation optimally manages to minimize power losses, improve voltage levels, fulfilling the objective of minimum cost.
