The steady-state operation of the EDS is represented using the real and imaginary parts of voltages and currents at nodes and circuits respectively. Distributed generation (DG) and the imbalance of the system circuits and loads are taken into account. The developed method defines an optimal charging schedule for the EVs. This charging schedule considers the EVs' arrival and departure times and their arrival state of charge, along with the energy contribution of EVs equipped with V2G technology.

The charging schedule obtained was compared in terms of V2G and DG scenarios, demonstrating the efficiency of the proposed method.72596607CAPESCNPqFAPESPCPFLCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Optimal Volt-var Control Operation For Finergy Cost Reduction In Distribution Systems Considering A Voltage Dependent Load Model

In 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.IEEE PES Transmission & Distribution Conference and Exposition-Latin America (PES T&D-LA)SEP 20-24, 2016Morelia, MEXIC
