Analysis Providing Diesel-Wind Hybrid Electrical Energy System in Timor Island Indonesia

The research objective are: (1) Analyse the capacity needs of the wind energy system based on the parameters of energy requirements, the ability of the inverter, generator capability and the ability of the local wind. (2) Generate a simulate diesel-wind hybrid power plants for Kupang city and every district in Timor island; (3) Generate an optimization of wind-diesel hybrid power plant for Kupang city and districts in Timor island; (4) Generate a scheme wind-diesel hybrid power plant for Kupang city and every district in Timor island. The method used in this research is quantitative method with the approach of simulation, optimization and sensitivity analysis used HOMER application program, i.e.: (1) simulation system of diesel-wind hybrid power plant; (2) optimization system of diesel-win hybrid generator, and (3) the sensitivity analysis system diesel-wind hybrid power plant. Conclusion of this research are: (1) Simulation in Kupang city and districts of Kupang are wind turbines 20 KW with generator capacity of 71.7 KW. Optimization result of wind-energy contribution of only 7% and ideal price of US $ 0.47 to produce wind turbines of 20,000 KWH/yr; (2) Simulation in South Central Timor (TTS) district is wind turbines 3 KW with generator capacity of 11.4 KW. The result of optimization of wind-energy contribution of only 9% and ideal price of US $ 0.525 to produce wind turbines of 1.165 KWH/yr; (3) Simulation in North Central Timor (TTU) district is wind turbines 1 KW with generator capacity of 7.62 KW. Optimization result of wind-energy contribution of only 4% and ideal price of US $ 0.53 to produce wind turbines of 1.150 KWH/yr;(4) Simulation in Belu districts is wind turbines 10 KW with generator capacity of 12.1 KW. Optimization result of wind-energy contribution of only 22% and ideal price of US $ 0.48 to produce wind turbines of 1.210 KWH/yr.
