摘要
为促进清洁能源消纳及多能耦合系统灵活运行,降低源、荷不确定性对系统的影响,构建包含光热电站的风光电热氢综合能源系统(wind-photovoltaic-electric-heat-hydrogen integrated energy system,WPEHHIES),提出一种鲁棒性可调的空间多面体不确定集两阶段鲁棒优化方法。基于列与约束生成(column-andconstraint generation,C&CG)算法将两阶段三层min-max-min鲁棒优化模型分解为一层min主问题与两层max-min子问题,通过强对偶原理将双层子问题结构简化处理;由子问题与主问题的交替求解,进而得到原问题的最优解。最后,通过算例分析验证所构建模型和求解算法的有效性及多能耦合系统出力的灵活性。
In order to improve clean energy consumption and flexible operation of multi energy coupling systems,while reducing the impact of source and load uncertainties on the system,this paper constructs a wind-photovoltaicelectric-heat-hydrogen integrated energy system(WPEHH-IES)including concentrating solar power,and proposes a two-stage robust optimization method with adjustable robustness for spatial polyhedral uncertainty sets.Based on the column-and-constraint generation(C&CG)algorithm,a two-stage three-layer min-max-min robust optimization model is decomposed into a one-layer min main problem and two-layer max-min subproblem.The structure of the two-layer subproblem is simplified by using the strong duality principle,and the optimal solution of the original problem is obtained by alternating the subproblem and the main problem.Finally,the effectiveness of the constructed model and solving algorithm,as well as the flexibility of the output of the multi energy coupling system,were verified through example analysis.
