Using PSO for optimal planning, and reducing loss of distribution networks

In this paper the practical planning of distribution system includes the selection of optimal conductor size and capacitor placement in radial distribution network considering increasing rate of loads. Technical operational constraints are available conductors and capacitors, voltage limit, maximum permissible carrying current of conductors and maximum reactive power could be injected. The power loss minimization problem is solved using particle swarm optimization (PSO). By applying this method, final cost of network planning, losses and their cost are considerably reduced and voltage profile of the network has improved to a semi-flat shape. Simulation results are investigated on a practical radial distribution network in Iran (Miandoab 20 kv distribution network), in addition self supporting cables are used for optimization which avoids illegal use of electricity.
