The power generation sector accounts for a significant portion of GHG emissions, and many countries strive for the large-scale adoption of renewable generation. Although the intermittent nature of renewables brings about complications in energy system planning, the share of renewable generations is increasing to the greatest extent. The wind generation has drawn increasing attention to expanding the use of renewable energy to reduce carbon emissions from the power generation sector, and the estimation of capacity factor is crucial in energy system modeling. This study develops a mathematical model for estimating the capacity factor of a wind farm with the consideration of outage probability of individual turbines. In addition, the power curves and wind speed distribution of the wind farm need to be estimated, which is demonstrated with a wind farm in Korea. It is asserted that the proposed method may render the wind farm capacity factor effectively. Thus, the results from this study can be useful for energy system modeling involving wind generations.

High costs, unreliable resources for long term use and extensive negative impact on our environment are such problems associated with traditional sources of energy and fossil fuels which make us move toward implementation of renewable sources of energy. Fossil fuel pollution and reserve depletion in oil producing countries caused by increasing demands, make wind energy an attractive source of energy in the future. Renewable energy sources are expected to have an important role in many countries as well as Iran and would be flourished in near future. In this study we aim to offer economic evaluation of wind turbine installation for chabahar in southeastern part of Iran. This study evaluates the economic feasibility of electricity generation using wind turbines in Chabahar - Iran situated in the Southeast part of Iran. All analyzes were performed by Homer software and local weather information and software provided by NASA Weather Homer is used. In this study 5 MW wind turbine with INVELOX technology is used .The analysis results show that Annual average of wind speed is 4.11 m/s at a Height of 10 m and 905 Gwh is the average of annual energy production, the cost of energy is calculated of 2.3 cents/kwh.
