Optimal selection of conductors in Egyptian radial distribution systems using sine-cosine optimization algorithm

Optimal conductor selection can reduce the electrical power losses and enhance the voltage profile of electrical power systems in a cost-effective manner. In this paper, a recent population-based optimization, known as sine-cosine optimization algorithm (SCA), is used for the optimal selection of conductors in radial distribution networks. A current library of conductors based on actual manufacturer data that include twenty different types of conductors is employed. The proposed algorithm is applied to a real Egyptian distribution system. The achieved results revealed the effectiveness of the SCA in reducing the network losses while maintaining the specified constraints over a ten-year period taking into account high annual load growth rate.
