This paper presents a strategy for solving the allocation problem of sectionalizing switches in a Brazilian electrical distribution system. The method used considers the fault history of the system during one year and the optimization of two contrasting objective functions: the continuity index DEC (Equivalent Duration of Interruption per Consumer Unit) and the total cost related to the sectionalizing equipments, such as: manual and automatic switches and automatic reclosers. The problem's optimal solutions acquisition is accomplished through the application of a multi-objective evolutionary algorithm, the NSGA-II (Elitist Non-Dominated Sorting Genetic Algorithm II), which works very well with the optimization of two objectives. The efficiency of the proposed strategy is tested in a Radial Distribution System (SDR) of Companhia Paulista de Força e Luz (CPFL) which has 2257 bars and 25521 consumers and seeks to minimize the number of switches devices used in the system as well as to improve the DEC reliability index. |
