Abstract

Jaring Distribusi Radial adalah jaring yang paling banyak digunakan untuk distribusi listrik karena arsitektur yang sederhana dan biaya investasi yang rendah. Pesatnya pertambahan pelanggan mengakibatkan jaring distribusi menjadi tidak seimbang dan terdistorsi harmonisa. Hal-hal ini menyebabkan jaring distribusi mengalami rugi-rugi daya yang besar. Rugi-rugi daya dapat diatasi dengan pemasangan kompensator daya reaktif, namun, kompensator daya reaktif ini harus dipasang secara benar untuk menghindari peningkatan harmonisa melebihi standar IEEE 519-1992. Oleh karena itu, pada makalah ini diusulkan Direct Search Algorithm (DSA) untuk menyelesaikan penempatan kapasitor pada jaring distribusi tidak seimbang dan terdistorsi harmonisa. Loss Sensitivity Factor (LSF) digunakan untuk menentukan calon lokasi dengan pengurangan kerugian daya maksimum. Algoritma yang diusulkan telah diuji pada sistem uji IEEE jaring distribusi radial 13 bus. Perbandingan kinerja DSA dilakukan melalui pencarian penurunan rugi-rugi daya maksimum untuk tiga kasus yaitu tanpa penempatan kapasitor, tanpa batasan THD dan dengan batasan THD. Hasil penelitian menunjukkan bahwa strategi yang diusulkan pada kasus ketiga memberikan penghematan lebih besar dari kasus-kasus lain. ========== Radial Distribution System is the most widely used system for power distribution because it has simple architechture and low investment costs. In contrast, due to the addition of the customers some challenges are rised about power system losses, unbalance issues and spread of harmonics which are both single phase and three phase customers. The power system losses can be overcome with the proper installation of reactive power compensator. This reactive power compensator must be installed approriately to avoid the system harmonic level exceeding the IEEE 519-1992 standard. Capacitor will be installed for compensating reactive power to maintain the voltage profile of the system. To overcome this problem, an effective algorithm is needed to identify the optimal location and capacity of capacitor in this system. This study will use harmonic power flow for distribution system. The load flow calculated voltage profile and harmonic distortion level on each bus voltage. Direct Search Algorithm works with loss sensitivity factor to find the most appropriate location and capacity of reactive power compensator without increasing harmonic distortion on the system. By considering THD, the best and location and capacity of reactive power compensator will be yielded while maintaining the voltage profile and minimize the power system losses.
