A new benders decomposition approach to solve power transmission network design problems

In this paper we describe a new Benders decomposition approach to solve power transmission network expansion planning problems, This new approach is characterized by using a linear (0-1) disjuntictive model which ensures the optimality of the solution found and by using additional constraints, iteratively evaluated, besides the traditional Benders cuts. The results obtained, considering a real world power transmission network expansion planning study with the southeastern Brazilian system, show the efficiency of this approach.
