| 电动汽车以及分布式能源的规模化接入对配电网的安全经济运行提出了巨大的挑战。考虑到交直流混合配电网(HADDN)具有灵活可控性高、分区特性显著的特点，提出了一种计及源-荷侧双重不确定性的HADDN有功功率和无功功率的分布式协同优化方法。首先，提出了综合考虑交通拓扑结构、居民出行行为以及风电预测误差区间差异性的电动汽车充电负荷-风电场景生成方法，采用基于Wasserstein距离的最优场景缩减算法生成典型概率场景；其次，建立了以网络损耗和节点电压偏差最小为目标的HADDN随机优化模型；然后，对所提多目标优化模型进行目标分解以及区域解耦，采用一种基于目标值交换原理的交替方向乘子法对其进行分布式求解；最后，通过算例仿真验证了所提方法的有效性。 |

| Abstract: |
| The large-scale access of EVs(Electric Vehicles) and distributed energy has posed great challenges to the safe and economic operation of distribution networks. Considering that HADDN(Hybrid AC/DC Distribution Network) has the characteristics of high flexibility and controllability and significant partitioning features, a distributed cooperative optimization method of HADDN active and reactive power considering the dual uncertainties of source side and load side is proposed. Firstly, the EV charging load-wind power scenario generation method is proposed, which comprehensively considers the traffic topology structure, the residents’ travel behavior and the interval difference of wind power prediction error. The optimal scenario reduction algorithm based on Wasserstein distance is used to generate typical probability scenarios. Secondly, the stochastic optimization model of HADDN is established to minimize the network loss and node voltage deviation. Then, the objective decomposition and region decoupling of the proposed multi-objective optimization model are performed, and the alternating direction method of multipliers based on the objective value exchange principle is used to solve the above model. Finally, the effectiveness of the proposed method is verified by a numerical example. |
