Analisa Pengaruh Pemasangan Distributed Generation Terhadap Profil Tegangan Pada Penyulang Abang Karangasem

Abstract — One technique to improve the voltage drop is with the installation of Distributed Generation. One of the Distributed Generation technologies in Bali is PLTS Kubu Karangasem which is a small scale electric generator that uses renewable energy, such as air, water, sun, geothermal, sea wave, ocean current, biomass and biogas to generate electrical energy. The electrical power that can be generated of 1 MW. Analysis using Load Flow Analysis Voltage Profile, the voltage drop reached 13,23 % when not connected to DG whereas connected to DG 10,85 % of voltage drop found when it was not connected to DG. Operation DG from 7:00 am to 17:00 pm can reduce the voltage drop during the morning at 8:00 amount 2,22 %, at 12:00 amount 3,17 % and at 17:00 voltage drop amount 1,78 %. Installation of DG interconnection on feeder Abang managed to reduce power losses with the amount of 1.023,682 kWh from total power losses that happened before the installation of DG on feeder Abang.
