| 摘要: |
| 交直流混合配电网是未来电网的一个重要形态，其能量管控研究具有重要意义。对多源并入的交直流混合配电网搭建局部和区域双层调度模型，提出交直流混合配电网的分布式调度优化策略。在局部调度层，考虑可再生分布式能源和储能设备联合出力，保证对负荷的平稳供给，并将优化调度结果上传给区域调度层；在区域调度层，对交流区域和直流区域各自进行独立优化，充分考虑各区域的自主运行特性，同时满足交直流混合配电网的运行约束条件，并提出基于一致性理论的分布式能量管控方法，获得最优可行解。算例结果验证了所提策略的有效性。 |

| Abstract: |
| AC/DC hybrid distribution network is an important form of future power grid, and its energy management research is of great significance. A local and regional bi-layer scheduling model is built for AC/DC hybrid distribution network with multiple sources, and a distributed scheduling optimization strategy is proposed. In the local dispatching layer, the joint output of renewable distributed energy and energy storage equipment are considered to ensure stable supply of load, and the optimal dispatching results are transmitted to the regional dispatching layer. In the regional dispatching layer, independent optimization is carried out for AC and DC regions respectively, the autonomous operation characteristics of each region are fully considered, the operation constraints of AC/DC hybrid distribution network are satisfied, and a distribu-ted energy management method based on consistency theory is proposed to obtain the optimal feasible solution. Case results verify the effectiveness of the proposed strategy. |
