On the optimal reconfiguration of radial AC distribution networks using an MINLP formulation: A GAMS-based approach

This paper deals with the problem of optimal reconfiguration medium voltage distribution networks by proposing a mixed-integer nonlinear programming (MINLP) model. optimization model has as objective function minimization total power losses in all branches network constrained active and reactive balance equations, regulation bounds device capabilities, among others. The proposed MINLP formulation works branch-to-node incidence that allows representing flow real imaginary parts voltages currents. solution is reached through general algebraic modeling system widely know GAMS package presenting it tutorial form. software implementing compact form solve via branch bound methods. Two test feeders composed 5 14 nodes permits demonstrating fidelity regarding when compared literature reports.
