Distribution Network Reconfiguration with Binary Particle Swarm Optimization to Reduce Power Loss in Kuta

The distribution system has several problems such as power losses and voltage drop. This problem also occurs in the 20 kV Kuta distribution system. Therefore, network reconfiguration and planning are needed to overcome the problem of power losses and voltage drop. In this study, reconfiguration was carried out on the 20kV Kuta distribution network system using the Binary Particle Swarm Optimization (BPSO), which aims to reduce power losses in the network. Next, the newton-raphson method in the Matpower 7.1 plugin is used to calculate the power flow. From the simulation results, before reconfiguration, the power loss results are 44.283 kW and 13.187 kVAR during non-peak load conditions, while the peak load time conditions are 51.087 kW and 14.711 kVAR. After network reconfiguration, the active and reactive power losses decreased to 27.489 kW and 10.64 kVAR for non-peak load (NPL) conditions, 31.21 kW and 13.654 kVAR for peak load (PL) conditions.
