Optimization of Network Reconfiguration in the ULP Way Halim Distribution System, Bandar Lampung City Considering the Use of Nonlinear Loads

Harmonic Distortion is a problem that is a challenge in itself in maintaining the quality of electric power due to the use of nonlinear loads. Network reconfiguration is considered capable of improving distribution system performance by operating a tie switch until an optimal configuration is obtained. This study aims to optimize network reconfiguration techniques to minimize total channel power losses and % THDv using the Particle Swarm optimization (PSO) method which was tested on the ULP Way Halim Electrical System, Bandar Lampung City 88 buses. The optimization results obtained a decrease in the total power loss of the channel by 64.75 kW or 79.51% and reduced the % THDv value.
