本文将尾流效应明确地引入风电场可靠性评估中。由此产生的能量损失被计入可靠性指标的计算中。讨论了尾流效应的三种模型，并采用Jensen模型进行了研究。在该模型中，风幕、切变效应和风向也被考虑在内。在计入尾流效应后，采用蒙特卡罗方法计算可靠性指标。考虑了风电场模型和风电场负荷与风速的相关性。使用国家可再生能源实验室的风速数据和IEEE可靠性测试系统的负载，将所提出的方法应用于风力发电场。仿真结果表明，该方法在实际应用中是有效和高效的。
In this paper, wake effect is explicitly incorporated in the reliability evaluation of a wind farm. Energy loss resulting from this effect is included in calculating the reliability indices. Three models for wake effect are discussed and the Jensen model is used in this research. In this model, wind shade, shear effect, and wind direction are also reflected. After incorporating the wake effect, the Monte Carlo technique is used to compute reliability indices. Wind farm model and correlation between load and wind speed are considered. The proposed methodology is applied to a wind farm using wind speed data from the National Renewal Energy Laboratory and load from IEEE Reliability Test Systems. The simulation results show that the proposed techniques are effective and efficient in practical applications.
