| 建立一种源荷不确定性条件下的微电网日前调度模型以提高其运行经济性。针对光伏功率和负荷构成的源荷不确定性,提出一种新颖的基于自适应优化决策的分布鲁棒优化方法,来克服传统鲁棒优化在不确定性处理中的过度保守问题。首先,构造一种保守性可调的源荷不确定性模糊集,利用分布约束灵活调节模糊集的保守性,同时引入辅助不确定性变量将该模糊集转换为易处理形式。其次,基于无限规划问题对偶原理和对偶变量固定,将分布不确定性降维成场景不确定性。最后,利用极端对偶变量生成技术将所提模型转换成两阶段求解的确定性规划。数值仿真验证了所提模型在平衡微电网运行经济性和鲁棒性上的优越性。 |
| 英文摘要: |
| A day-ahead dispatch model for microgrids under source-load uncertainty conditions is established to enhance their economical effectiveness. In view of the source-load uncertainty composed of photovoltaic power and demand, a novel adaptive optimization decision-based distributionally robust optimization is proposed to overcome the conservativeness of traditional robust optimization. Firstly, a conservativeness-adjustable ambiguous set of source-load uncertainty is constructed, which can flexibly adjust the conservatism through distribution constraints. Meanwhile, auxiliary uncertainty variables are introduced to transform the ambiguous set into a manageable form. Secondly, leveraging the duality principle of infinite programming and fixing the dual variables, the distribution uncertainty is reduced to scenario uncertainty. Finally, employing an extreme dual variable generation method, the proposed model is converted into a deterministic programming in a two-stage solving framework. Numerical simulations verify the superiority of the proposed model in balancing the economical effectiveness and robustness of microgrid operations. |
