More Information
Summary:Tiga Nusa is a region consist of three small islands: Nusa Penida, Nusa Lembongan, and Nusa Ceningan, that located southeast of Bali Island. Those three small islands have many magnificent diving sports that are famous among divers all over the world. Therefore, this region becomes one of tourist attraction initiate rapid development. Energy demand in this region is increasing significantly. The power supply of this region is isolated from Bali Island. The utility company is trying to get supply from Bali Island by connecting this region through 20kV submarine cable. This paper presents the load flow analysis and supply security analysis of the Tiga Nusa system before and after the submarine cables operated. Load flow analysis has found that power loss increase when submarine cable operates. Voltage drop is not significantly improved but it moved from Nusa Lembongan to Nusa Penida. However the supply security is until year 2033 if 2 submarine cables operate.
