Eka Fitrianto, Refdinal Nazir

Abstract


Electrical systems supplied from a substation (GI) which is quite far away from the center of the furthest load will cause a voltage drop in radial distribution network. Integration of distributed generation (Distributed Generation, DG) on the distribution network will be one of the solutions to improve the voltage drop. This paper analyzes integrating several distributed generation (DG) in a radial distribution network to repair a voltage with Matlab program. Method using flow injection analysis of load and DG on each bus. The analysis showed that the penetration of DG on the distribution network will improve bus voltage, especially at bus adjacent to the DG.

Keywords: distributed generation (DG), radial distribution, voltage drop, integration.


Abstrak— Pada sistem distribusi radial 20 kV yang suplainya dipasok oleh Gardu Induk (GI) dalam jarak yang cukup jauh dari pusat beban akan menyebabkan terjadinya penurunan tegangan. Pengintegrasian pembangkit tersebar (Distributed Generation, DG) pada jaringan distribusi tersebut akan menjadi salah satu solusi untuk memperbaiki penurunan tegangan tersebut.  Tulisan ini menganalisis pengintegrasian beberapa pembangkit listrik tersebar (DG) pada suatu jaringan distribusi radial terhadap perbaikan tegangan dengan program Matlab.  Metoda analisis menggunakan arus injeksi dari beban dan DG pada setiap bus. Hasil analisis menunjukkan bahwa penetrasi DG pada jaringan distribusi akan memperbaiki tegangan bus terutama pada bus yang berdekatan dengan DG.

Kata Kunci : Pembangkit  listrik  tersebar(DG), distribusi radial,  perosotan tegangan, Arus injeksi.
