Loss Minimization and Congestion Management of a Power Distribution Network through its Reconfiguration

Reduction of loss in a power distribution network is of utmost importance for any electrical utility. Recent years have seen development of various optimization techniques and computer technology which has made it possible to perform accurate analysis of distribution losses. The network reconfiguration of a distribution network is done by changing the status of sectionalizing switches by switching operation. It is done usually to minimize the loss and to avoid overloading. In this paper the objective is to find a method by which management of distribution system loss by network reconfiguration can be done so that all the loads receive power. The developed program is made flexible for checking many conditions at a time and compares them with the rated condition to find the best condition with minimum loss and identifies occurrence of any overload. A method using Smart wire is also suggested for congestion management under overload conditions.
