| 摘要: |
| 当因输电通道限制需对风电集群进行限电时，应考虑各风电场功率预测和调节能力的差异。考虑功率预测偏差和调节能力不确定性，构建机会约束规划和机会约束目标规划相结合的风电集群日前功率调度模型，并采用采样排序的方法将不确定变量转化为确定性变量对模型进行求解。对华北某地区风电集群进行案例分析，结果表明，在满足风电场间期望调度电量比例要求的基础上，相较于传统模型，所提模型能有效降低弃风率和系统负荷不平衡时的缺额电量。 |

| Abstract: |
| When it is necessary to limit the power of wind power cluster due to the restriction of transmission channel, the difference of power forecasting and regulation capacity of each wind farm should be considered. Considering the power forecasting deviation and the uncertainty of regulation capacity, a day-ahead power dispatching model of wind power cluster combining the opportunity constrained programming and opportunity constrained goal programming is constructed, and the sampling and sequencing method is adopted to transform the uncertain variables into deterministic variables for solving the model. The wind power cluster in a region of North China is taken for example analysis, and results show that on the basis of satis-fying the requirement of expected dispatching electricity quantity ratio, compared with the traditional model, the proposed model can effectively reduce the wind abandon rate and the shortage of electricity quantity when the system load is unbalanced. |
