Convergence Rate Assessment in Optimal Re-closers Placement

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.
