  • This paper presents a new and efficient methodology for distribution network reconfiguration integrated with optimal power flow (OPF) based on a Benders decomposition approach. The objective minimizes power
    losses, balancing load among feeders and subject to constraints:
    capacity limit of branches, minimum and maximum power limits of
    substations or distributed generators, minimum deviation of bus voltages
    and radial optimal operation of networks. The Generalized Benders
    decomposition algorithm is applied to solve the problem. The formulation
    can be embedded under two stages; the first one is the Master problem
    and is formulated as a mixed integer non-linear programming problem.
    This stage determines the radial topology of the distribution network.
    The second stage is the Slave problem and is formulated as a non-linear
    programming problem. This stage is used to determine the feasibility of
    the Master problem solution by means of an OPF and provides information
    to formulate the linear Benders cuts that connect both problems. The
    model is programmed in GAMS. The effectiveness of the proposal is
    demonstrated through two examples extracted from the literature.
