چکیده مقاله:
Distribution Network Reconfiguration (DNR) and optimal placement of Distributed Generators (DGs) are two major approaches to reduce losses of distribution networks. Inthis paper a new method to reduce network loss with the simultaneous utilize of these two issues is presented. For thispurpose, the DNR and determining sizing and sitting of DG ismodeled as an optimization problem for minimizing the total loss of the system considering operation constraints. Anevolutionary algorithm called Invasive Weed Optimization (IWO) algorithm is used to solve this problem. Moreover, thegraph theory and tree condition for a graph are used for radiality checking during the DNR problem solution. The proposed method is applied to both IEEE 33-Bus radial testsystem and Khoram Abad city real network. Assessment alloptimization results show the effectiveness of the proposed method for loss reduction.
