| 摘要: |
| 风电容量可信度是衡量风力发电对电力系统可靠性贡献的重要指标，准确快速地计算风电场可信容量是含风电系统规划的基础。处于同一风区空间位置临近风电场出力具有相关性，采用Copula函数描述空间相邻风电场之间的出力相关关系，构建多风电场出力的联合概率分布模型。在此基础上提出出力相关的多风电场容量可信度评估方法，并采用截弦法计算得到风电场的容量可信度。以加入风电的IEEE RTS-96系统为例，仿真结果验证了所提方法的正确性和有效性。 |

| Abstract: |
| The wind-power capacity credibility is an important indicator to measure its contribution to power system reliability and the quick and accurate calculation of wind-power credible capacity is the foundation of system planning including wind power. There is the power output correlation among nearby wind farms in same wind area，which is described by Copula function for building the joint power output probability distribution model of multiple wind farms. A method of capacity credibility assessment considering the power output correlation of multiple wind farms is proposed and the secant method is adopted to calculate the capacity credibility of wind farm. As an example，the simulative results for IEEE RTS-96 system with added wind power show the correctness and effectiveness of the proposed method. |
