Resumen

This paper presents a multiobjective optimization method, using an enumerative procedure for determining the optimal number and the optimal locations of sectionalizing switches and protective devices, in order to achieve the best ENS (Energy Not Supplied) reliability index with minimal investment cost in distribution network systems with several substations (STR). To achieve this, two objective functions are optimized: one defined by an ENS reliability index and the other defined by the economic investment costs. From all the achieved solutions, the non-dominated solutions are selected, which represent the best results for each economic investment. Thus, the planner can utilize a support tool for decision-making regarding investment and installation of sectionalizing switches and protective devices, taking into account the technical and economic limitations imposed by the electric utility. © (2014) Trans Tech Publications, Switzerland.
