Abstract
Sistem distribusi PLN ULP Pasangkayu masih mengalami penurunan tegangan meskipun telah menggunakan kapasitor bank konvensional di tiga titik lokasi. Penelitian ini bertujuan mengoptimalkan penempatan dan ukuran kapasitor bank dinamis menggunakan algoritma turbulensi aliran air untuk meningkatkan stabilitas tegangan dan mengurangi rugi-rugi daya. Metodologi penelitian mencakup pemodelan sistem distribusi pada ETAP untuk menganalisis kondisi eksisting dan titik undervoltage, serta pemrograman algoritma turbulensi aliran air di MATLAB untuk proses optimasi. Fungsi objektif diformulasikan untuk meminimalkan deviasi tegangan dan rugi-rugi daya. Penelitian ini menggunakan empat skenario simulasi yang diuji pada empat skenario yaitu , skenario pertama tanpa kapasitor, skenario kedua kapasitor eksisting, skenario ketiga optimasi lokasi kapasitor menggunakan TWFO, dan skenario keempat optimasi lokasi dan ukuran kapasitor dinamis
Simulasi keempat dengan optimasi turbulensi aliran air untuk lokasi serta ukuran kapasitor dinamis di pilih karena menghasilkan pengurangan rugi daya sebesar 76,4% dari rugi daya awal 3,65 MW menjadi 0,86 MW serta menghasilkan perbaikan tegangan dan stabilitas sebesar 18,27 % dari 16,14 kV menjadi 19,09 kV dan seluruh busbar memenuhi batas tegangan ≥18 kV. Selain itu, perhitungan keekonomian menunjukkan nilai payback period < 3 tahun, membuktikan kelayakan teknis dan finansial implementasi kapasitor dinamis berbasis turbulensi aliran air dan memberikan konfigurasi kapasitor dinamis yang lebih efektif dibandingkan metode konvensional, baik dalam peningkatan profil tegangan maupun efisiensi energi

The PLN ULP Pasangkayu distribution system still experiences voltage drops despite using conventional capacitor banks at three locations. This study aims to optimize the placement and size of dynamic capacitor banks using an airflow turbulence algorithm to improve voltage stability and reduce power losses. The research methodology includes modeling the distribution system in ETAP to analyze existing conditions and undervoltage points, as well as programming the airflow turbulence algorithm in MATLAB for the optimization process. The objective function is formulated to minimize voltage deviation and power losses. This study used four simulation scenarios tested: the first scenario without capacitors, the second scenario with existing capacitors, the third scenario optimizing capacitor locations using TWFO, and the fourth scenario optimizing dynamic capacitance location and sizing.
The fourth simulation, which optimized airflow turbulence for the location and size of dynamic capacitors, was chosen because it resulted in a 76,4% reduction in power losses from an initial 3,65 MW to 0,86 MW, and an 18,27% improvement in voltage and stability from 16,14 kV to 19,09 kV, ensuring all busbars met the voltage limit of ≥18 kV. Furthermore, economic calculations showed a payback period of <3 years, proving the technical and financial feasibility of implementing turbulence water flow-based dynamic capacitors and providing a more effective dynamic capacitor configuration than conventional methods, both in terms of improving the voltage profile and energy efficiency.
