可再生能源与HVDC系统协调运行的氢气管道P2G集群的技术经济补充
Technoeconomic Supplement of P2G Clusters with Hydrogen Pipeline for Coordinated Renewable Energy and HVDC Systems
摘要：
在可再生能源发电机价格下降和氢气需求上升的趋势下，研究了P2G集群与氢气管道对高压直流输电共同消耗可再生能源的技术经济补充。首先，建立了大容量P2G集群的规划和运营约束。在此基础上，综合考虑可变性和不确定性，建立了可再生能源、HVDC、P2G和氢气管道的多阶段协调规划模型，给出了分布式鲁棒机会约束（DRCC）规划。并以蒙鲁系统为例进行了实证研究。与仅通过高压直流输电的能量传输相比，P2G可以以其运营灵活性和长期经济性提供运营补充，以满足高价值运输部门不断增长的需求，这刺激了额外的24 GW可再生能源勘探。技术和经济因素的敏感性分析进一步验证了P2G在可再生能源的高波动性和可再生能源发电机价格下降趋势下的优势。然而，由于P2G的额外平准化成本（0.04元人民币/千瓦时）约为HVDC（0.02元人民币/千瓦时）的两倍，因此P2G对可再生能源和氢气需求的不确定性更加敏感。
英文摘要：
Under the downward tendency of prices of renewable energy generators and upward trend of hydrogen demand, this paper studies the technoeconomic supplement of P2G clusters with hydrogen pipeline for HVDC to jointly consume renewable energy. First, the planning and operation constraints of large-capacity P2G clusters is established. On this basis, the multistage coordinated planning model of renewable energy, HVDCs, P2Gs and hydrogen pipelines is proposed considering both variability and uncertainty, rendering a distributionally robust chance-constrained (DRCC) program. Then this model is applied in the case study based on the real Inner Mongolia-Shandong system. Compared with energy transmission via HVDC only, P2G can provide operation supplement with its operational flexibility and long term economic supplement with increasing demand in high-valued transportation sector, which stimulates an extra 24 GW renewable energy exploration. Sensitivity analysis for both technical and economic factors further verifies the advantages of P2G in the presence of high variability due to renewable energy and downward tendency of prices of renewable energy generators. However, since the additional levelized cost of the P2G (0.04 RMB/kWh) is approximately twice the HVDC (0.02 RMB/kWh), P2G is more sensitive to uncertainty from both renewable energy and hydrogen demand.
