Compensación de potencia reactiva en redes de distribución de media tensión mediante compensadores conmutados basados en tiristores aplicando el algoritmo del colibrí artificial

Abstract

This document presents an innovative metaheuristic algorithm designed to solve the reactive power compensation problem in medium-voltage distribution systems, utilizing Thyristor-Controlled Series Compensators (TCSC). The primary objective of this methodology is to minimize the annual operating costs of the network by optimizing its efficiency and performance. The problem is tackled using a master-slave approach with discrete-continuous coding, allowing for an effective integration of decision-making in the master stage and a detailed evaluation of the solutions in the slave stage. The proposed methodology employs the Artificial Hummingbird Algorithm to generate potential solutions to the problem in the master stage. These solutions are encoded to suit the optimization framework and then evaluated in the slave stage through a successive approximation power flow method. This process enables the identification of optimal configurations for the placement and sizing of reactive power compensators, such as TCSC devices, at strategic nodes in the distribution network. To validate the effectiveness of the proposed methodology, tests were conducted on two distribution systems with configurations of 33 and 69 nodes, respectively. The results reveal a significant reduction in network energy losses when TCSC compensators are integrated, demonstrating the potential of the Artificial Hummingbird Algorithm to enhance the operation and efficiency of distribution systems. These findings confirm the capability of the proposed methodology to effectively address the reactive power compensation problem and contribute to the development of more efficient and reliable distribution networks.
