This situation requires new analysis tools for understanding system performance, and taking advantage of the potential benefits of DG. This paper presents an evolutionary multi-objective programming approach to determine the optimal operation of DG in distribution systems. The objectives are the minimization of the system power losses and operation cost of the DG units. The proposed approach also considers the inherent stochasticity of DG technologies powered by renewable resources. Some tests were carried out on the IEEE 34 bus distribution test system showing the robustness and applicability of the proposed methodology. © 2011 IEEE.257-262engDistributed generationEvolutionary multi-objective programmingPower lossesAnalysis toolsDG technologyDG unitDistributed GenerationDistributed generationsDistribution systemsMultiobjective programmingOperation costOptimal operationPotential benefitsPower-lossesRenewable resourceStochasticityTest systemsDistributed power generationMultiobjective optimizationDistributed computer systemsTrabalho apresentado em evento10.1109/TDC-LA.2010.5762891Acesso aberto2-s2.0-79957535661
