| 摘要: |
| 目前基于矩的分布鲁棒优化方法没有很好地考虑风电不确定参数间的相关性导致方法比较保守。考虑风电的不确定性和相关性，使用主元分析方法构建基于矩的分布鲁棒多区域电网经济调度模型的降维模糊集。将原始模型转化为半定规划模型，并采用延迟约束生成算法进行求解。算例仿真结果表明所提方法可以提高计算效率以及降低电网成本。 |

| Abstract: |
| The current moment based distributionally robust optimization method does not properly consider the correlation among uncertain parameters of wind power, which causes conservativeness of the method. Considering the uncertainty and correlation of wind power, the principal component analysis method is used to build a dimensionality reduced ambiguity set of moment based distributionally robust economic dispatch model for multi-regional power grid. The original model is transformed into a semidefinite programming model, and solved by the delayed constraint generation algorithm. The simulative results of case show that the proposed method can improve calculation efficiency and reduce power grid cost. |
