摘要: 为了研究可再生能源制氢和沼气发酵在农村综合能源系统中的调度作用,考虑沼气发酵动力学模型和热负荷特征,构建集成光伏制氢、热电联产、沼气发酵、能量存储的电-热-冷-气综合能源系统模型,建立以日运行成本最小为目标的两阶段鲁棒优化日前调度模型,并基于列约束生成(C&CG)算法进行求解,得到系统在最恶劣场景下的日前调度计划。此外,根据光伏发电和电负荷短期预测值进行日内调度,实现了系统在功率平衡条件、设备运行约束下的可靠、经济运行。针对农村农业园区综合能源系统进行的算例分析结果表明:光伏制氢和沼气发酵具备储能特性及其对“源-荷”不确定性的消纳作用,且验证了该特性带来的一定经济性。

Abstract: This paper aims to investigate the dispatch role played by renewable energy hydrogen production and biogas fermentation in the rural integrated energy system. Firstly, based on the biogas fermentation kinetics model and thermal load characteristics, we constructed an electricity-heat-cold-gas integrated energy system model, which consists of PV hydrogen production, combined heat and power generation, biogas fermentation and energy storage. Then, we established a two stage robust optimization based day-ahead dispatch model with the goal of minimizing daily operation cost, and obtained the day-ahead dispatch plan under the worst scenario by solving the model with column-and-constraint generation (C&CG) algorithm. Moreover, we finished the intra-day dispatch in light of short-term forecasting value of PV power and electric load, realizing the stable and economic operation of the integrated energy system. Finally, a case study was conducted on a rural agricultural park integrated energy system, which indicates that the PV hydrogen production and biogas fermentation have energy storage characteristics and can make contributions to alleviate “source-load” uncertainty, and are proved to have a certain economic value.
