提出一种风电场可靠性模型，该模型考虑风电机组故障，将风电场可用容量的概率分布与可用风能的概率分布相结合，计算出风电场输出功率的概率分布，然后将输出功率离散到数个降额运行出力水平，将风电场等效为一个多状态常规机组。模型不仅适用于由同种风电机组组成的风电场，还可用于由多种不同型号风电机组组成的风电场，可方便地应用于解析法和模拟法来评估风电场接入对电力系统可靠性的影响，以简化含大型风电场电力系统可靠性评估的复杂程度。以IEEE—RTS79系统为算例，验证了所述模型的有效性。

A reliability model of wind farm is proposed. The output of wind farm is considered to obey a joint probability distribution of available capacity and available wind energy. In this study, the wind farm is equivalent to a multi state conventional unit by dispersing the output into several derating output levels. The model allows the simulation of wind farms containing either identical or different wind turbine types. The model can be easily used in the power system reliability assessment utilizing analytical or simulation methods to simplify the reliability assessment of power system containing large-scale wind farm. Finally, a case study is carried out on IEEE-RTS 79 test system to verify the effectiveness of the model.
