A new approach for distribution feeder reconfiguration for loss reduction and service restoration

This paper presents a new approach lo solve the distribution feeder reconfiguration problem for loss reduction and service restoration By using the proposed algorithiii, a more effcieiit network configuration can be obtained to reduce loss. Three switching indices were defined in this paper. Branch voltage-drops and line constants were used wit11 all tlie electrical constraints. Meshed networks were considered instead of tlie radial topology by closing all the tie switclics. By considering only the largest switching index in each loop, this algoritliiii can reduce the number of feasible states drastically. Tlie switching index can also be used for service restoration. Many tests have been run to sIio\v its e~kctivencss.
