This paper presents a new application of particle swarm optimization (PSO) and fuzzy logic in feeder-switch relocation. In the simulation-based experimentation, the radial distribution system used as the distribution system. The simulation result has shown that PSO is able to search the most appropriate positions to place sectionalized devices in distribution lines. In other words, various suitable patterns for installing sectionalized devices in distribution lines can be discovered by using PSO. Consequently, the line crew can make a decision in choosing the best pattern based on the value-based distribution reliability, the power system techniques, the environmental condition and the convenience in operation. Fuzzy logic can assist in risk analysis of interruptions caused by trees. That affects directly the failure rate of an overhead line distribution system.
