ANALISA PERBANDINGAN METODE ANT COLONY OPTIMIZATION DAN ARTIFICIAL BEE COLONY DALAM MENGOPTIMASI PENEMPATAN RECLOSER UNTUK MENINGKATKAN KEANDALAN SISTEM DISTRIBUSI 20 KV PADA PENYULANG DAMPIT.

The distribution system is an electrical energy system that has a function to distribute electrical energy sources to customers. The quality of distribution system reliability can be seen from the frequent occurrence of blackouts within a certain period of time. Basically the distribution system has two parameters, namely SAIDI (Standard Average Interuption Duration Index) and SAIFI (Standard Average Interuption Frequency Index). Protection devices that are usually used to increase the reliability of distribution systems include recloser. Recloser is a protection device that can detect overcurrent disturbances due to short circuits, either temporary or permanent. In this study, we will discuss a comparative analysis of the Artificial Bee Colony and Ant Colony Optimization methods in optimizing recloser placement to increase the reliability of the 20 kv distribution system on the Dampit feeder. In testing using Ant Colony Optimization on the placement of 2 reclosers, the SAIDI value is 6.8991 hours/year and the SAIFI value is 2.0520 times/year with recloser placement on bus 13 and bus 39 with a fitness value of 0.0706. Meanwhile, for the placement of 3 reclosers, the SAIDI value is 7.3667 hours/year and the SAIFI value is 2.2134 times/year with the recloser placement on buses 26, 34, and 39 with a fitness value of 0.0613 towards convergence
