摘要

针对综合能源系统中可再生能源消纳难题与低碳化发展需求，提出一种考虑燃气机组掺氢与燃煤机组掺氨联合运行的优化调度方法。首先，充分考虑风电与光伏出力的不确定性及其相关性，采用基于Frank Copula函数的风光联合出力建模方法，通过边缘分布拟合、蒙特卡洛采样与K-means聚类等步骤生成典型风光联合出力场景，用于提升调度模型的鲁棒性；同时，构建电制氢与氢转氨的能量转化模型，实现可再生能源向氢、氨能源的高效转化；其次，针对传统化石能源机组的低碳改造需求，建立燃气机组掺氢燃烧和燃煤机组掺氨燃烧的精细化运行模型，优化氢氨燃料在发电环节的协同利用方式；然后，结合阶梯型碳交易机制，以系统总运行成本最小为目标构建优化调度模型，并采用CPLEX求解器进行求解；最后，设置不同场景并进行对比分析。结果表明，在氢能利用基础上进一步考虑氢转氨，减少了系统的弃风弃光现象；掺氢燃气机组与掺氨燃煤机组联合运行使系统总运行成本和碳排放量均得到减少。该研究可为综合能源系统的低碳化发展提供参考。

Abstract

Aiming at the difficulties in renewable energy consumption and the demand for low-carbon development in the integrated energy system

an optimal scheduling method considering the joint operation of hydrogen-doped gas-fired units with hydrogen-doped and ammonia-doped coal-fired units is proposed. Firstly

to account for the uncertainty and correlation of wind and solar power outputs

a joint wind-solar output modeling approach based on the Frank Copula function is adopted. Typical wind-solar scenarios are generated through marginal distribution fitting using kernel density estimation

Monte Carlo sampling

and K-means clustering

thereby enhancing the robustness of the scheduling model. Meanwhile

energy conversion models for power-to-hydrogen and hydrogento-ammonia processes are developed to enable the efficient transformation of renewable energy into hydrogen and ammonia. Secondly

the refined operation model of hydrogen-doped combustion of gas-fired units and ammoniadoped combustion of coal-fired units is constructed in response to the demand for low-carbon transformation of conventional fossil energy units

so as to optimize the synergistic utilization of hydrogen and ammonia fuels in the power generation process. Then

the optimal dispatching model is constructed by combining with the ladderingtype carbon trading mechanism with the goal of minimizing the total operation cost of the system

which is to minimize the total cost of the system. Moreover

the optimal scheduling model is constructed with the objective of minimizing the total operating cost of the system in combination with the stepped carbon trading mechanism and solved by the CPLEX solver. Finally

different scenarios are set up and comparative analysis are carried out. The results indicate that

the introduction of hydrogen-to-ammonia conversion

building upon hydrogen energy utilization

significantly mitigates wind and solar power curtailment within the system. The combined operation of hydrogen-doped gas-fired unit and ammonia-doped coal-fired unit leads to concurrent reductions in both total operational costs and carbon emissions. The study provides a reference for the development of decarbonization of integrated energy systems.
