The short-term scheduling procedure adopted in the paper is composed by two stages: a day-ahead scheduler for the optimization of distributed resources production during the following day, an intra-day scheduler that every 15 minutes adjusts the scheduling in order to take into account the operation requirements and constraints of the distribution network. The intra-day scheduler solves a non-linear multi-objective optimization problem by iteratively applying a mixed-integer linear programming (MILP) algorithm. The linearization of the optimization function and the constraints is achieved by the use of sensitivity coefficients obtained from the results of a three-phase power flow calculation. The paper shows the application of the proposed approach to a medium-voltage 120 buses network with 10 dispatchable generators and 2 transformers equipped with on-load tap changers. © 2009 IEEE.Distributed generationMILPOperation of distribution networksDistributed resourcesDistribution management systemsDistribution networkDistribution systemsMedium voltageMixed-integer linear programmingMulti-objective optimization problemNon-linearOn-load tap changersOptimization functionReactive power compensatorSensitivity coefficientShort-term schedulingThree-phase power flowTwo stageDistributed parameter networksDistributed power generationElectric load managementEmbedded systemsInteger programmingLinear programmingLinearizationMultiobjective optimizationPower transformersVoltage controlDistribution functionsepfl-smartgridstext::conference output::conference proceedings::conference paper
