摘要

为优化沙戈荒新能源大基地煤电机组掺烧绿氢降碳的系统配置方案，构建了一套包含制氢、储氢、储能及煤电机组掺氢燃烧的综合系统框架，建立了降碳目标约束下以氢燃料成本最低为目标的系统配置优化模型，并运用混合整数线性规划方法进行求解与分析，探讨了不同运行场景下的降碳系统配置优化方案。以某沙戈荒新能源大基地为例，在单台煤电机组降碳10%的目标约束下，如仅利用弃风弃光电力制氢时，制氢装置年利用小时数仅约2 000 h，标准状态下绿氢成本高达3.02元/m

(33.80元/kg)，单台煤电机组度电成本增加0.217 9元/(k W·h)；配置电化学储能可降低制氢、储氢系统配置规模，提升制氢装置利用小时数，但受限于高额的储能建设成本，储能规模需要优化确定，标准状态下绿氢成本最低可降至约2.35元/m

(26.30元/kg)，单台煤电机组度电成本增加0.165 2元/(kW·h)；在储能基础上，如可在绿氢认证范围内引入少量公网电力辅助制氢，可进一步减少系统建设成本，标准状态下制氢成本有望降低至约2.12元/m

(23.70元/kg)，单台煤电机组度电成本增加0.142 6元/(kW·h)。

Abstract

To optimize the system configuration scheme for green hydrogen co-firing in coal-fired power units at large renewable bases in desert

gobi

and wasteland areas to achieve decarbonization

a comprehensive system framework encompassing hydrogen production

hydrogen storage

energy storage

and hydrogen co-firing in coalfired power units is established. It develops a system configuration optimization model aiming f

or the lowest hydrogen production cost under a decarbonization target constraint. The model is solved and analyzed using mixedinteger linear programming to explore the optimal configuration solutions for a decarbonization system via green hydrogen co-firing in different operating scenarios. The model is demonstrated through a case study. Under the constraint of 10% decarbonization for a single coal-fired power unit

if only curtailed wind and solar power are used for hydrogen production

the annual utilization hours of the hydrogen production equipment are only about 2 000 hours

and the green hydrogen cost is as high as 3.02 yuan/m

(33.8 yuan/kg). This leads to an increase of 0.217 9 yuan/(kW·h) in the per-unit electricity cost for a single coal-fired power unit. Configuring electrochemical energy storage can reduce the scale of hydrogen production and storage systems and increase the utilization hours of hydrogen production equipment. However

limited by high energy storage construction costs

the energy storage scale needs to be optimally determined

and the green hydrogen cost can be reduced to approximately 2.35 yuan/m

(26.3 yuan/kg) at its lowest

which leads to an increase of 0.165 2 yuan/(kW·h) in the per-unit electricity cost for a single coal-fired power unit. Furthermore

if a small amount of grid electricity can be introduced to assist hydrogen production within the scope of green hydrogen certification

system construction costs can be further reduced. The hydrogen production cost is expected to decrease to approximately 2.12 yuan/m

(23.7 yuan/kg) and the per-unit electricity cost for a single coal-fired power unit would increase by 0.142 6 yuan/(kW·h).
