Rediseño óptimo de redes radiales de distribución eléctrica en bajo voltaje considerando las restricciones de la infraestructura eléctrica y urbana existente

Abstract

For distribution companies, a primary objective is to minimize the levels of electrical losses, which represents efficiency and sustainability. The methodology focuses on the minimization of costs for determining the number and location of transformers. It takes into consideration the demands of subscribers and the restrictions of electrical and urban infrastructure, so that the results of the redesign are perfectly applicable to current circuits. The proposal is divided into three STAGES, the first defines the optimal location of transformers through the use of partitioning methods, genetic algorithms, and graph theory, in the second stage through the model of optimal conductor selection and investment costs of transformers, determines the total costs of the circuit, in the last stage is determined the optimal number of transformers using the elbow method. For the development of the work is considered an aerial and radial test circuit that is currently supplied by 10 transformers. The results obtained from the redesign show that the implementation of this represents a cost saving of 58.208% with respect to the current state of the network.
