Dimensionamiento óptimo de generación solar fotovoltaica en redes de distribución para minimizar las pérdidas anuales de energía y el índice de desviación de voltaje considerando un algoritmo híbrido basado en ramificación y acotamiento

Abstract

This paper is focused on the optimal location and sizing of distributed generation considering solar photovoltaic energy in radial distribution systems. The main objective is to minimize annual energy losses and the voltage deviation index in a percentage manner. A 33-bus IEEE radial test system is implemented to be analyzed by the hybrid branching and bounding algorithm in Matlab software considering different restrictions. Among the benefits obtained, the significant reduction of annual energy losses stands out, which translates into lower operating costs and greater sustainability of the system. Likewise, the decrease in the voltage deviation index contributes to maintaining voltage levels within acceptable ranges, favoring the quality of the electrical supply. The results obtained were validated, thus minimizing annual energy losses and voltage deviation to achieve an improvement in both the reliability and quality of electrical energy.
