Abstract

The present research project intends to carry out a theoretical analysis and the computational implementation of a reformulated tabu search algorithm applied to the problem of reconfiguration of primary feeders in radial electric energy distribution systems. Thus, it is intended to develop a tabu search algorithm that, from an initial solution proposal, finds optimal or near-optimal solutions using a reformulated proposal. The tabu search algorithm that is intended to be developed should not use the list of prohibited attributes and the aspiration criteria. Thus, the algorithm does not store attributes to avoid revisiting solutions already visited in the iterative process. This goal is achieved by storing complete solutions. This proposal is sensible because in the reconfiguration problem, the number of iterations is very small when compared to other complex problems in the field of operational research. It is intended to test the performance of the algorithm using data from existing systems available in the specialized literature. (AU)
