This research deals with the efficiency comparison between AC and DC distribution networks that can provide electricity to rural urban areas from point of view grid energy losses greenhouse gas emissions impact. Configurations for medium- low-voltage are analyzed via optimal power flow analysis by adding voltage regulation devices capabilities sources in mathematical formulation. Renewable resources such as wind photovoltaic considered using typical daily generation curves. Batteries formulated a linear representation taking into account operative bounds suggested manufacturers. Numerical results two electrical 0.24 kV 12.66 (with radial meshed configurations) performed constant loads at all nodes. These simulations confirm technology is more efficient regarding losses, profiles than its counterpart. All numerical tested General Algebraic Modeling System widely known GAMS.
