| 摘要: |
| 提出了一种改进相关矩阵蒙特卡罗模拟法与拉丁超立方采样法相结合的多维相关风速抽样方法，并把该方法应用于含多个风电场的发输电系统可靠性评估。通过实际风速数据对模型的验证表明：提出的风速相关模型能够充分保持实际风速数据的概率分布，基本统计量和相关特性。将该模型和方法应用到 MRTS可靠性测试系统中，证明了该方法适用于含具有风速相关性的风电场的发输电系统可靠性评估。并通过算例，对风速相关性程度、风电场接入位置和风能渗透水平三个因素对含风电场的发输电系统可靠性的影响进行了分析。 |

| Abstract: |
| This paper presents a sampling method of multidimensional correlated wind speed that combines with improved correlation matrix Monte Carlo simulation method and Latin hypercube sampling method. The proposed method has been applied to composite generation and transmission system reliability evaluation with multiple wind farms. The tests using actual wind speed data verify that the proposed model for wind speed correlation can capture the statistical properties of actual wind speeds, including probability distributions, basic statistics and correlations. The results from the application of the proposed method to the MRTS reliability test system demonstrate that this method is appropriate for reliability evaluation of composite generation and transmission system containing multiple wind farms with correlations. And according to some examples, the effects of wind speed correlation, position of wind farm and wind power penetration level on composite generation and transmission system reliability including wind farms are analyzed. |
