Minimum loss reconfiguration of unbalanced distribution networks

A heuristic method for determining the configuration with minimum resistive line losses for three-phase unbalanced distribution networks is described. This method is based on previous papers dealing with balanced network [1,2,3]. Using a fast and reliable load flow solution technique and also, efficient algorithms for network elements inspection, so that methodology becomes capable to solve the challenging problem while still maintaining a high execution speed. A developed algorithm is applied on a practical distribution network. Performed analysis highlight the influence of load imbalances on a solution of minimum loss reconfiguration problem.
