Mixed-integer linear programming model for solving reconfiguration problems in large-scale distribution systems

Abstract: An improved mixed-integer linear program for determining the tree of minimum active power losses in balanced large medium voltage systems is presented and assessed throughout this paper. The proposed approach depends on a number of parameters, which can be tuned for each specific system, ensuring a desired level of accuracy in relation to the final obtained solution. Eight systems were tested with the new algorithm to highlight the efficiency and accuracy of the proposed model. The model is mainly designed for large systems with a high number of switches whose statuses need to be determined. [Copyright &y& Elsevier]
