چکیده

In this paper, two protective devices, recloser and cutout fuse, are placed simultaneously. Indeed, main contribution of this research is considering Distribution Generation (DG) placement in this problem. The multi objective function has been formulated based on minimizing power loss and maximizing reliability. Selection of reliability indices has been performed based on a compromise between customer satisfaction and seller. This problem is solved by Particle Swarm Optimization (PSO) algorithm and tested on the part of practical distribution system. The reliability indices are System Average Interruption Duration Index (SAIFI), Cost of Energy Not Supplied (CENS), System Average Interruption Frequency Index (SAIFI) and Momentary Average Interruption Frequency Index (MAIFI). Simulation has been performed in part of practical distribution system by introduced several scenarios and cases.
