Distribution network reconfiguration for loss reduction using ant colony system algorithm

In Electrical Power System, Network reconfiguration for loss reduction in distribution systems is very important way to save energy. But due to its nature it is inherently a difficult optimization problem. Distribution system reconfiguration for loss reduction is being applied using Ant Colony System Algorithm where in, the behavior of the real ants is developed into a series of steps which find most efficient in the network reconfiguration. Ants of the artificial colony are able to search for the successively shorter feasible routes by using information accumulated in the form of a pheromone trail deposited on the edges of their traveling path. In this work we make use of conventional distribution system load flow algorithm to check the constraints. Power flow constraints, the voltage deviation and the power transferred through the line should be met. A distribution network consisting of 14-bus system with three feeders, 19-branches and It-load centers from Tamil Nadu Electricity Board (TNEB) is taken as case study. The results outstand positively forming an optimal network.
