Özet:

Wind resource assessments are required to identify a specific area capable of producing valuable energy from wind speeds. This paper aims to optimize wind assessment through wind farm siting and layout in Indonesia’s semi-arid region. Wind data collected on Sumba Island over a one-year period was analyzed to assess the area's wind energy potential. Wind Atlas Analysis and Application Programme (WAsP) and Windographer were used to generate a generalized wind climate and resource maps for the area. Wind farm layout and preliminary turbine micro-sitting were completed with various scenarios in mind to achieve the best possible result. Four different scenarios are considered to maximize power output. There are 34 identical wind turbines with a unit capacity of 90 kW in Scenario 1. Scenario 2 includes 20 identical wind turbines with a total capacity of 3000 kW. In Scenario 3, 14 identical wind turbines with 225 kW of unit capacity are used. There are 12 identical wind turbines with a unit capacity of 250 kW in Scenario 4. The results showed that scenario 1 produced the highest total net Annual Energy Production (AEP) of 11,287 MWh/year with a 3.73 % wake loss. The minimum wake loss seemed to be 2.62 % in scenario 4, with a total net AEP of 10,22MWh/year.<
