NARVAEZ, Pablo A; LOPEZ-LEZAMA, Jesús M  and  VELILLA, Esteban. Location of Distributed Generation for Power Losses Reduction using a Hybrid Genetic Algorithm. Inf. tecnol. [online]. 2015, vol.26, n.3, pp.123-132. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000300016.

This paper presents a methodology for optimal Distributed Generation (DG) allocation using a hybrid genetic algorithm. In this case, the objective function is the minimization of power losses. The proposed algorithm involves an artificial neural network to evaluate the fitness function and a local search subroutine that allows the algorithm to explore a wider search space, and eventually, escape from local optimal solutions. The proposed approach was tested on a 34-bus system showing that the proper allocation of DG units allows the reduction of active power losses and the improvement of voltage profile.

Keywords : genetic algorithms; distributed generation; artificial neural networks.
