| 摘要: |
| 针对微电网群作为市场主体接入配电网引起的利益冲突问题，提出一种微电网群多阶段鲁棒优化规划方法。基于主从博弈理论建立配电网与微电网群的双层规划数学模型：上层为配电网优化运行模型，以降低运行成本并提升电压水平为目标；下层为微电网群优化规划模型，解决微电网群内电源的容量配置问题。考虑到负荷增长的不确定性，在模型中增加鲁棒优化，以提升规划方案的鲁棒性。采用卡罗需-库恩-塔克(KKT)条件将原始问题转换成单层均衡约束数学规划问题，并利用列和约束生成(C&CG)算法进行求解。IEEE 33节点系统算例结果表明，所提方法提升了配电网对可再生能源的消纳能力且改善了配电网的运行指标，同时又保证了微电网投资商的经济利益，有效实现了配电网与微电网的协调发展。 |

| Abstract: |
| Aiming at the interest conflict problem caused by the access of microgrid clusters into distribution network as market entities, a multi-stage robust optimization planning method of microgrid clusters is proposed. A double-layer planning mathematical model of distribution network and microgrid clusters is built based on the master-slave game theory. The upper layer is the optimal operation model of distribution network, aiming at reducing operating cost and improving voltage level. The lower layer is the optimization planning model of microgrid clusters, which solves the capacity configuration problem of sources in microgrid clusters. Considering the uncertainty of load growth, the robust optimization is added in the model to improve the robustness of the planning scheme. The KKT(Karush-Kuhn-Tucker) condition is adopted to convert the original problem into a single-layer equilibrium constraint mathematical programming problem, and the C&CG(Column-and-Constraint Generation) algorithm is used to solve the problem. The example of IEEE 33-bus system shows that the proposed method improves the consumption ability of distribution network for renewable energy and improves the operating indexes of distribution network, while ensures the economic benefit of microgrid investors and effectively realize the coordinated development of distribution network and microgrid. |
