多类型源储协调互动的配电网分布鲁棒优化调度

分布式光伏、风电等可再生能源出力具有较强的随机性和不确定性，其大量并网给配电网的运行带来了极大的挑战。本文提出了一种多类型源储协调互动的配电网分布鲁棒优化调度方法，基于分布鲁棒优化理论，对配电网中传统离散设备、可再生能源以及储能决策进行协调优化，提高配电网运行的经济性和安全性，实现了配电网运行决策保守性与鲁棒性的有效平衡。首先，考虑多类型源储资源的协调互动，建立配电网优化调度模型，并将其转化为混合整数二阶锥规划的形式；其次，利用可再生能源出力场景集进行不确定性刻画，建立分布鲁棒优化模型，并通过列和约束生成算法进行求解；最后，在PG&E69节点系统上进行算例分析，验证了所提方法的可行性与准确性。

Distributionally robust optimal dispatch of distribution network considering multiple source-storage coordinated interaction

Renewable energy sources (RES) such as distributed photovoltaic (PV) and wind turbine (WT) provide uncertain and stochastic active power supply, then the large amount of RES has brought great challenges to the operation of distribution network. This paper proposes a distributionally robust optimal dispatch method considering multiple source-storage coordinated interaction for distribution network. Based on the distributionally robust optimization theory, the dispatch decisions of traditional discrete devices, RES and energy storage are optimized coordinately to improve the economy and safety of distribution network operation, and to realize the effective balance of conservativeness and robustness for dis-tribution network dispatch decision. Firstly, with consideration of multiple source-storage coordinated interaction, the optimal distribution network dispatch model is constructed, and then it is reformulated as the mixed integer second-order cone programming form. Secondly, the RES output scenarios are utilized to describe the uncertainty while the distribu-tionally robust optimal dispatch model of distribution network considering multiple source-storage coordinated interac-tion is constructed, after which the column and constraint generation algorithm is employed for model solution. Finally, an example analysis is carried out based on the PG&E69 node system to verify the feasibility and accuracy of the proposed method.
