Analysis of conductor selection for loss reduction in RDS using DPSO

The economic conductor sizing in radial distribution system is major importance. The optimal conductor selection is to select a type of conductor so as to minimize the objective function, which is sum of depreciation on capital investment and energy loss while satisfying the maximum current carrying capacity and minimum voltage levels. The conductor, which is determined by this method, will satisfy the maximum current carrying capacity and maintain acceptable voltage levels of the radial distribution systems. In addition, this method gives maximum saving in the capital cost of conducting material and cost of energy losses.
