Rekonfigurasi Jaringan Distribusi untuk Meminimisasi Rugi-Rugi pada Penyulang Kabut di Gardu Induk Teluk Betung Menggunakan Metode Binary Particle Swarm Optimization (BPSO)

Distribution network reconfiguration is needed to minimize losses, especially in densely populated areas. Various reconfiguration methods and techniques have been proposed for the purpose of minimizing power losses. This paper presents a reconfiguration of the distribution network using the binary particle swarm optimization (BPSO) with a case study in Kabut feeder at the Teluk Betung substation. Reconfiguration is performed only by creating new lines without changing the number of lines. The results showed that with the planned four new lines, BPSO method can find new configuration to further minimizes losses. Active power losses resulting from the new configuration is 47.1043 kW or decreased by 1.81% of active power losses before the reconfiguration, i.e. 47.9477 kW. Voltage profile on each bus is better than those of before reconfiguration, where the minimum voltage obtained is 0.98603 per unit compared with a minimum voltage of 0.98597 per unit prior to reconfiguration. However, the selection of the best initial position of the whole of particle swarms outside loop configuration formed by new lines may cause a failure to find the best configuration
