Alocação de subestações e alimentadores no planejamento da expansão de sistemas de distribuição via sistema imunológico artificial

Abstract

This work proposes a method for solving radial distribution systems expansion problems, making a multi-purpose analysis that includes the allocation of new substations, reconditioning of existing substations and sizing feeders selecting the path of the circuits for feeding the fillers and the type of conductor used in each section. The presented optimization problem seeks to minimize overall system costs, involving physical, technical and operational constraints. Many systems found in the literature were used for the test method and the results were compared, showing that the method can also be applied to other systems, including large others. The technique used was based on the metaheuristic Artificial Immune System, which uses basic concepts of immunology for solving combinatorial optimization problems.
