AEP calculation for offshore wind farm considering wind direction uncertainty
摘要
Abstract
The Lillgrund offshore wind farm is taken as a toy example. Larsen wake model and linear wake summation method are adopted to establish wind farm power and AEP calculation models. Considering about the yaw misalignment of reference wind turbine, the post-processing model based on gaussian averaging (GA) is proposed for wind power correction. Based on the analysis of measured data and convergence process of AEP calculations, the effects of GA model on wind power and AEP calculations are discussed. Analysis shows, the established wind power calculation model can well reflect the wake characteristics in a real wind farm. Besides, GA corrections can not only improve the precision of the calculated wind farm output power, but also speed up the convergence of AEP calculation process. Taking wind direction uncertainty into consideration is an excellent way to improve the accuracy of wake model evaluations and validations.关键词
