Abstract
Sistem jaringan distribusi radial memiliki kualitas tegangan yang buruk dan kerugian daya yang tinggi. Berbagai teknik kompensasi daya telah dikembangkan oleh para insinyur dan peneliti untuk menjaga kualitas daya yang ditransmisikan ke pelanggan. Dalam tugas akhir ini, dilakukan skema perencanaan injeksi daya aktif dan reaktif dengan menggunakan kombinasi sistem penyimpanan energi baterai dan kapasitor bank untuk menangani kerentanan jaringan terhadap drop tegangan dan inefisiensi sistem. Simulasi dilakukan pada sistem IEEE 33 bus modifikasi dengan metode optimasi algoritma particle swarm optimization (PSO). Simulasi dilakukan dalam 4 variasi meliputi base case, optimasi kapasitor bank saja, optimasi baterai saja, optimasi baterai dan kapasitor bank secara bersamaan. Pada variasi kondisi dasar (base case), tegangan minimum selama 24 jam adalah 0,93161 pu, dan biaya kerugian daya aktif harian adalah $217,16. Pada variasi optimasi kapasitor bank saja, jumlah kapasitor bank yang optimal adalah 2. Dalam variasi ini tegangan minimum selama 24 jam adalah 0,95000 pu dengan biaya kerugian daya aktif harian adalah $158,41. Pada variasi optimasi baterai saja, jumlah baterai yang optimal adalah 2. Dalam variasi ini, tegangan minimum selama 24 jam adalah 0,95051 pu dengan biaya kerugian daya aktif harian sebesar $182,22. Pada optimasi kapasitor dan baterai secara bersamaan didapatkan kombinasi optimal adalah 2 kapasitor bank dan 1 baterai. Dalam variasi ini, tegangan minimum selama 24 jam adalah 0,95009 pu dengan biaya kerugian daya aktif adalah $157,50. Kemudian, dari hasil analisa ekonomi dengan perencanaan pemasangan 10 tahun didapatkan biaya penghematan terbesar adalah variasi penempatan 2 kapasitor bank. Pada variasi ini biaya penghematan yang terjadi selama 10 tahun sebesar $183164,5.

Radial distribution network systems have poor voltage quality and higher power losses. Various power compensation techniques have been developed by engineers and researchers to maintain the quality of power transmitted to customers. In this final project, an active and reactive power injection planning scheme is carried out using a combination of a battery energy storage system and a capacitor bank to deal with network susceptibility to voltage drops and system inefficiencies. The simulation was carried out on a modified IEEE 33 bus system with the particle swarm optimization (PSO) algorithm optimization method. Simulations were carried out in 4 variations including base case, capacitor bank optimization only, battery optimization only, battery optimization and capacitor bank simultaneously. In the base condition variation, the minimum voltage for 24 hours is 0.93161 pu, and the daily active power loss cost is $217.16. In the optimization variation of the capacitor bank only, the optimal number of capacitor banks is 2. In this variation the minimum voltage for 24 hours is 0.95000 pu with a daily active power loss cost of $158.41. In the battery optimization variation only, the optimal number of batteries is 2. In this variation, the minimum voltage for 24 hours is 0.95051 pu with a daily active power loss cost of $182.22. In the simultaneous optimization of capacitors and batteries, the optimal combination is 2 capacitor banks and 1 battery. In this variation the minimum voltage for 24 hours is 0.95009 pu with a power loss cost of $157.50. Then, from the results of an economic analysis with a 10-year installation plan, it was found that the biggest cost savings is the variation in the placement of 2 capacitor banks. In this variation the cost savings that occur are $183164.5.
