Adequacy study of wind farms considering reliability and wake effect of WTGs

The wake effect of a wind turbine generator (WTG) may affect output of a wind farm. Wake effect depends on wind speed, and the size and location of WTGs in a wind farm. When one or more WTGs fail in a wind farm, the wind speed distribution in the farm will change, which may lead to different wind power output from the farm. This paper proposes a Monte Carlo simulation technique is used to evaluate adequacy of a wind farm with considering the reliability and location of WTGs, wind speed and the wake effect of WTGs. A quadratic interpolation method is used to study the optimal distribution of WTG in a wind farm. Reliability of a wind farm with and without the optimal WTG distribution is investigated by using the proposed technique. The results show that, the optimal layout of a wind farm with considering wake effect should be considered in wind farm adequacy studies.
