Aplicación del algoritmo de optimización aritmética al problema de balance de fases en sistemas de distribución asimétricos

Abstract

This article presents the application of the Arithmetic Optimization Algorithm (AOA) to address the phase balancing problem in asymmetric electrical distribution systems. The MATLAB software is employed for the implementation of this algorithm, and a comparative analysis is conducted between the results obtained from the networks presented in specialized literature and those obtained using other optimization algorithms, with a focus on power losses. The main objective of this study is to determine the optimal load connection at each node in order to minimize active power losses, which serves as the objective function within this context. The investigation is based on the standard IEEE test networks consisting of 25 and 37 nodes, specifically selected from specialized literature. A master-slave strategy is proposed, where the iterative power flow is programmed as the slave stage in its three-phase version. Power losses are analyzed under standard conditions of phase connections at the load. Following this, the Arithmetic Optimization Algorithm (AOA) is programmed as the master stage, leading to the identification of the most optimal connections to be implemented. These connections are compared and evaluated against alternative methodologies as well as the base case, aiming to assess their effectiveness in reducing power losses.
