摘要
微能源网是多能流耦合的微电网系统,为优化其设备容量配置,针对内部分布式可再生能源和负荷的不确定性,提出了综合范数约束下场景概率驱动的微能源网分布鲁棒规划方法。基于风-光出力和电-热-氢负荷的历史数据聚类提取典型场景,并构建基于1-范数和∞-范数约束的场景概率分布不确定集以描述源-荷不确定性。以年综合成本最低为目标建立min-max-min三层分布鲁棒规划模型,采用列与约束生成(column and constraint generation,C & CG)算法求解。仿真结果表明,引入所提场景概率不确定集和分布鲁棒模型后,系统年综合成本降低1.33%,且模型在经济性和鲁棒性的平衡方面相比传统随机优化和鲁棒优化更有优势,可在更短的迭代次数内降低年综合成本。
Abstract
As a multi-energy flow coupled microgrid system, optimized equipment capacity allocation for the micro energy grid is required, considering the uncertainties of internal distributed renewable energy and loads. A scenario probability-driven distributed robust planning method for the micro energy grid under comprehensive norm constraints was proposed, aiming to address the uncertainties of distributed renewable energy sources and electric-thermal-hydrogen loads. Historical data of wind-photovoltaic outputs and multi-energy loads were clustered to extract typical scenarios. An uncertainty set for scenario probability distributions was constructed based on 1-norm and ∞-norm constraints to characterize source-load uncertainties. A triple-layer min-max-min distributed robust optimization model was established with the objective of minimizing annual comprehensive costs, and the model was solved using the column and constraint generation (C & CG) algorithm. It is demonstrated by simulation results that a 1.33% reduction in annual comprehensive costs is achieved by the proposed uncertainty set and robust model compared to conventional approaches. Superior balance between economic efficiency and robustness is exhibited by the model over traditional stochastic and robust optimization methods, while fewer iterations are required for the model to converge. Decision-making adaptability against multi-dimensional uncertainties in renewable-dominated energy systems is effectively enhanced by this framework.
