Planificación óptima para la expansión del sistema de transmisión considerando reducción de pérdidas mediante optimización de enjambre de partículas

Abstract

In electrical power systems, it is essential to have a correct planning of transmission system expansion, takin into account line restrictions, for good system design. An analysis of power system reinforcement by means of an optimization algorithm, which allows to see the candidate lines that need to increase in the analyzed systems. For this study, an optimization base on particle swarming was implemented, considering transmission line restrictions and installation costs, applied to a static analysis for a specific year, where it seeks to find the best possible configuration to reduce system losses. The approach of the lines was divided into two scenarios where the first one was based on the reinforcement of the existing lines in the systems, the second scenario added the reinforcement with the approach of new connections between bars that presented a low voltage level and were considered a critical point for the reduction of losses. Finally, a comparative analysis was made between the original and optimized systems showing the voltage levels, the connected lines, and a percentage analysis of the loss reduction of the systems.
