This paper proposes the analysis of Sigmoid, Hyperbolic Tangent and Elliot functions in the PSO
algorithm for reconfiguration of electrical system. The aim of reconfiguration is to reduce losses in the electrical
system. The optimization algorithm used the binary PSO heuristic method and was developed in MATLAB©
software using the MATPOWER toolbox to solve the power flow. The reduction of real losses is the objective
function, where each particle is the state of the branch switch, open or closed. The methodology was applied to
the IEEE-30 Bus, IEEE-118 Bus and to a Planned Example Case of a Brazilian Power Distribution Company. It
was observed that the Hyperbolic Tangent and Elliot function performed well in optimizing the power system
reconfiguration to reduce losses in the IEEE-30 bus, IEEE-118 bus and 138 kV planned example case.
