摘　　要：分布式光伏不确定性给微电网稳定运行带来巨大挑战,为了提高微电网应对不确定性的能力和总体运行经济性,提出了一种基于豪斯多夫(Hausdorff)距离的微电网两阶段分布鲁棒经济优化调度模型。首先,基于分布鲁棒优化的方法,建立了含分布式光伏、储能、微型燃气轮机、常规负荷和需求响应负荷的微电网优化调度模型。然后,使用Hausdorff距离对模型中不确定场景及其概率分布集进行构建。最后,通过列与约束生成算法(column-and-constraint generation,CC&G)对模型求解,得到最优调度策略。算例对某居民微电网进行仿真,结果表明基于Hausdorff距离建立的概率分布集能有效提高模型经济性,且可以通过调整置信度控制模型鲁棒程度。在蒙特卡洛仿真实验中,验证了所提模型具有良好的鲁棒性。The uncertainty of distributed photovoltaics poses significant challenges to the stable operation of microgrids.To enhance the microgrid's capability to handle uncertainty and improve overall operational economy,a two-stage distributionally robust economic optimization scheduling model for microgrids based on the Hausdorff distance is proposed.First,an optimization scheduling model for a microgrid with distributed photovoltaics,energy storage,micro gas turbines,conventional loads,and demand response loads is established using the distributionally robust optimization approach.Next,the Hausdorff distance is employed to construct the uncertain scenarios and their associated probability distribution sets within the model.Finally,the model is solved using the column-and-constraint generation(CC&G)algorithm to obtain the optimal scheduling strategy.A simulation is conducted on a residential microgrid as a case study.The results demonstrate that the probability distribution set established using the Hausdorff distance effectively improves the model's economic performance and allows the robustness level to be adjusted by modifying the confidence level.The Monte Carlo simulation validates that the proposed model exhibits good robustness.
