Abstract

Energi listrik merupakan komoditi utama untuk menunjang kehidupan manusia di era digital saat ini. Penyaluran energi listrik dilakukan melalui pusat pembangkit besar di sejumlah lokasi. Sejak tiga dekade terakhir, terdapat banyak penelitian yang memfokuskan pada penggunaan DG untuk minimasi kerugian jarigan dan regulasi tegangan namun, sedikit yang memfokuskan kepada keandalan dari sistem jaringan distribusi energi listrik.  Penelitian ini bertujuan untuk mengetahui dampak yang dihasilkan jika mengkoneksikan DG ke jaringan distribusi energi listrik.  Data uji yang digunakan adalah system distribusi radial IEEE 33-bus. Algoritma PSO digunakan sebagai optimasi penentuan lokasi dan kapasitas dari DG.  Hasil penelitian menunjukkan bahwa terdapat perbedaan system jaringan distribusi radial tanpa DG, dengan 1 DG dan 2 DG. Total rugi-rugi system distribus tanpa DG adalah 208,52 KW dan 334,38 KVAr, sedangkan 1 DG menghasilkan rugi-rugi 1,94% dari total rugi-rugi dan 2 DG menghasilkan 1,09% dari total rugirugi.  Indicator keandalan system SAIDI tanpa DG yakni 4,7 jam/pelanggan.tahun dan mengalami perbaikan sebesar 27% dengan 2 DG. Sedangkan, inkator keandalan system SIAFI tanpa DG yakni 1,47 frekuensi/pelangggan.tahun mengalami perbaikan sebesar 4% dari dengan 2 DG.  Sehingga dapat disimpulkan bahwa penambahan DG dengan algoritma optimasi PSO menunjukkan hasil berupa pengurangan rugi-rugi, perbaikan profil tegangan disetiap bus, serta perbaikan keandalan sistem distribusi.
