The role of distributed generation (DG), a form of renewable energy generation that is spread out across the grid, has been continuously developed over the past decade with the aim of enhancing power system performance and supporting government programs like clean coal technology (CCL). The advancement of technology relies heavily on semiconductor devices, which are used in various applications such as electronic equipment and motor speed control systems. However, these devices have a negative impact on power quality by introducing harmonic distortion. Capacitors are widely used for reactive power compensation, but they can also cause harmonic resonance, as can DG units. Inverters in DG systems contribute to harmonic distortion in the grid. This study aims to analyze the effects of placing DG and capacitors sequentially using the Particle Swarm Optimization (PSO) method, taking into account the presence of harmonic loads in ULP Sungguminasa. The objective function (OF) focuses on reducing % THDv (total harmonic distortion voltage) and total losses (PLoss), tested through several case studies using MATLAB programming. The combination of DG and capacitor placement in Scenario 4 successfully increased efficiency, reducing the average % THDv value up to 19.26% and PLoss values by up to 20.26% or 78.97 kV A. the study could be extended to different grid configurations and consider the integration of other renewable energy sources to further validate and enhance the robustness of the proposed approach. © 2024 IEEE.
