The Public Electric Vehicle Charging Station (SPKLU) connected to the electrical distribution system acts as a non-linear load that has the potential to cause harmonic distortion, which can degrade power quality, increase energy losses, and pose risks to equipment and protection systems. This study analyzes the electrical system of ULP Karebosi, particularly the POLDA feeder, to evaluate the impact of non-linear loads on harmonic propagation and to determine the optimal placement of the SPKLU using the Particle Swarm Optimization (PSO) method with Forward Backward Sweep (FBS) and Harmonic Load Flow (HLF) approaches. The parameters analyzed include power loss (Ploss) and total harmonic voltage distortion (THDv). The results show that, at the initial placement on bus 29, the average voltage increased by 0.07%, %THDv rose by 41.11%, and the power loss reached 151.99 kW. After optimization using the PSO method, the SPKLU was relocated to bus 10, resulting in improved performance, where the average voltage increase dropped to 0.05%, %THDv decreased to 19.33%, and power loss was reduced to 140.64 kW. These findings demonstrate that optimal placement of the SPKLU can effectively mitigate harmonics, improve power quality, and reduce energy losses. © 2025 IEEE.
