Optimization Electricity Supply for Thousand Island Jakarta Province by Using Hybrid Photovoltaic-Wind Turbine-Diesel Generator-Crude Palm Oil (CPO) Power Plant-Battery System

The Thousand Islands as part of the DKI Jakarta Province which has more than 110 islands with an electrification ratio of 100%. The electricity supply for the inhabitant islands in Thousand Islands region is supplied by State Electricity Company (PLN) with the on-grid interconnecting system on the medium voltage marine line I (SKLTM) along 76.79 km. Meanwhile Sebira Island supplies electricity using the Diesel Power Plant (PLTD) provided by the Regional Government (PEMDA). To increase the reliability of the SKLTM line I system in the Thousand Islands, SKLTM line II will be built along 67.7 km in 2018-2021. Based on the description of the development plan, this paper will redesign the electricity supply system with 100% renewable energy power plants in each of the 11 inhabitant islands in the Thousand Islands, namely the hybrid system of Solar Power Generation (PLTS), Wind Turbine Power Plant (PLTB), Diesel Power Plant (PLTD) and Crude Palm Oil (CPO) Power Plant (PLTBn CPO). The average annual solar radiation in the Thousand Islands region is 5.08 kWh/m2/day and the annual average wind speed at an altitude of 50 m is 3.29 m/s. To optimize the hybrid system modeling, the Hybrid Optimization Model for Electric Renewable (HOMER) Pro 3.11.2 software version is used based on the lowest Net Production Cost (NPC) and Cost of Electricity (CoE) value. The study showed that 7 inhabitant islands are recommended using Hybrid PV-Wind-Diesel such as Sebira Island with percentage 59.3% (PLTS), 38.5% (PLTB) and 2.2% (PLTD) with CoE 0.178 $/kWh and NPC $1,092,096.Other 4 inhabitant islands are recommended using 100 % PLTBn CPO only such as Tidung Island with CoE 0.274 $/kWh and NPC $15,076,130.
