The reliability of the distribution system is improvedby the placement of protective devices at some costs which is aconcern. In this paper, the optimal number and locations of recloserfor a ۵۸ bus system are determined to maximize therevenue at minimum costs. The genetic algorithm (GA), particleswarm optimization (PSO), and Mayfly algorithm (MA) areutilized. Reliability indices such as SAIFI, SAIDI, CAIDI, ASAI& AENS before and after the placement of re-closers areassessed. The results obtained indicate that all three algorithmscan yield valuable results, however, PSO executes it much fasterwith a lower computation load.
