| 摘要: |
| 随着可再生分布式电源(RDG)在配电网中的渗透率逐步提高，局部地区已出现配电网对RDG消纳能力不足的情况。已有研究表明主动配电网中的各类有功、无功灵活性资源对RDG消纳具有促进作用。为此，基于氢储能的可移动特性，提出一种新型的含高密度RDG的主动配电网优化调度模型。考虑RDG出力的随机性和氢能在多座氢储能电站之间运输的时间约束，以及无功补偿装置、软开关等传统调节手段，提出了软开关模型精确线性化建模方法，建立了多座氢储能电站在配电网内的优化调度混合整数线性规划模型。以某一实际农村配电网为算例对所提方法进行仿真，量化分析了考虑可移动特性的多氢储能电站协同优化的效果，并验证了所提线性化模型的精确性。 |

| Abstract: |
| As the permeability of RDG(Renewable Distributed Generation) in distribution network increases gradually, the consumption capacity of distribution network to RDG is insufficient in some local areas. Stu-dies show that various active and reactive flexible resources in active distribution network can promote RDG consumption. Therefore, based on the mobile characteristics of hydrogen energy storage, a new optimal dispatch model of active distribution network with high-density RDG is proposed. Considering the randomness of RDG output and the transportation time constraint of hydrogen energy among multiple hydrogen energy storage stations, as well as the traditional regulation means such as reactive power compensation device, soft open point, and so on, an accurate linearized modeling method for soft open point is proposed, and the mixed integer linear programming model for optimal dispatch of multiple hydrogen energy storage stations in distribution network is established. A practical rural distribution network is taken as an example to simu-late the proposed method, and the collaborative optimization effect of multiple hydrogen energy storage stations considering mobile characteristics is quantitatively analyzed, and the accuracy of the proposed linear model is verified. |
