Lopez Lezama, Jesus Maria [UNESP]Padilha Feltrin, Antonio [UNESP]2014-05-272014-05-272009-11-27IET Conference Publications, n. 550 CP, 2009.http://hdl.handle.net/11449/71249This paper presents a methodology for the placement and sizing evaluation of distributed generation (DG) in electric power systems. The candidate locations for DG placement are identified on the bases of Locational Marginal Prices (LMP's) obtained from an optimal power flow solution. The problem is formulated for two different objectives: social welfare maximization and profit maximization. For each DG unit an optimal placement is identified for each of the objectives.engCandidate locationsDG unitDistributed GenerationDistributed generationsLocational marginal pricesOptimal placementsOptimal power flowsProfit maximizationSocial welfare maximizationDistributed power generationElectric power distributionElectric power measurementElectric power transmission networksElectric utilitiesGalerkin methodsOptimizationPower electronicsProfitabilityElectric generatorsTrabalho apresentado em evento10.1049/cp.2009.1103Acesso aberto2-s2.0-704501739093886842168147059
