| 摘要: |
| 针对联网运行的微电网，对其优化潮流（OPF）问题进行扩展，同时考虑机组组合（UC），建立微电网优化运行模型。针对模型中含有大量混合0／1决策变量和连续运行变量的求解，采用Benders分解方法将变量分离，在无网络约束UC主问题和网络约束OPF子问题之间迭代求解。在改造后的IEEE 13节点系统上进行了算例分析，表明所提方法可以快速可靠地优化微电网系统的运行。 |

| Abstract: |
| The optimal power flow problem is extended for the grid-connected microgrid and an optimal operation model with the consideration of UC（Unit Commitment） is built. The 0／1 decision variables and the continuous operational variables mixed in the model are separated by the Benders decomposition and solved by the iteration between the UC main problem without network constraints and the OPF sub-problem with network constraints. Case analysis of the modified IEEE 13-bus system verifies that the proposed method can quickly and reliably optimize the operation of microgrid. |
