CRESPO SANCHEZ, Gustavo et al. Review of the assignment of switches in the reconfiguration of distribution networks to maximize reliability and minimize costs. Universidad y Sociedad [online]. 2019, vol.11, n.1, pp. 339-349.  Epub 02-Mar-2019. ISSN 2218-3620.

Electric distribution networks are incredible and complex structures whose main function is to supply electric power to customers. Therefore, the planning areas must design systems with minimal cost, which can be operated in the most economical way and which guarantee customers an adequate voltage level, with undistorted waveforms and interruptions in supply and energy losses in the networks, be minimal. Optimal reconfiguration is one of the best solutions to achieve this. Generally, the minimization of active energy losses is considered, although during the last few decades, reconfiguration proposals have been developed to improve the reliability that allows minimizing maintenance costs and providing interruption free electricity services as well as the continuity of the service after failures. This article provides general background, review of the literature and comparative analysis of the methods used to assign switches in the reconfiguration of distribution networks to maximize reliability and minimize losses and costs, which can serve as a reference for the orientation of the new researchers in this field.

Palavras-chave : Network reconfiguration; switch allocation; reliability; power losses in networks; optimization.
