New York: Ieee, 6 p., 2016.2381-3571http://hdl.handle.net/11449/159322In this paper, a new mixed integer linear programming formulation is proposed to optimally control the Volt-VAr control devices installed in a balanced electrical distribution system (EDS), taking into account the presence of dispatchable distributed generation (DG) units. The formulation considers a voltage dependent load model and aims to reduce the cost of the energy purchased to the substation and DG units on a daylong time period. The proposed method defines the settings for the voltage regulators, on-load tap changer, capacitors, and DG units. The presented formulation was tested in a 42-node EDS and the obtained results prove that the methodology enhances the EDS economic operation with a very low computational effort.6engEnergy cost reductionmixed integer linear programmingvolt-var control operationvoltage dependent load modelTrabalho apresentado em eventoWOS:000392658600025Acesso aberto
