| 水利枢纽工程除了防洪、供水等常规功能外，还能促进风光能源高水平开发利用和区域生态保护。黄河流域几字弯区域风光资源丰富，但缺少灵活调节能力限制了区域内风光能源开发利用；此外，该区域煤炭开采和火电站运行给区域生态系统带来了极大的负担。本研究分析了黑山峡水利枢纽（规划装机容量为2000 MW）在促进几字弯区域风光能源开发利用中的关键作用，结果表明黑山峡水利枢纽结合抽水蓄能电站（规划装机容量为3000 MW），采取考虑基荷的常规运行方式可配套开发自身容量1.89倍的风光能源（风电3716 MW和光伏5760 MW）。采取无基荷要求的灵活运行方式可配套开发自身容量2.02倍的风光能源（风电4212 MW和光伏5888 MW），与常规运行方式相比具有更高的发电效益（7.12%）。进一步，本研究评估了依托黑山峡水利枢纽建成5888 MW光伏电站后可显著促进区域内植被恢复，植被净初级生产力每年可增加18.31×108 g DM（相当于减少1093吨标准煤排放的CO2）。综上，黑山峡水利枢纽具有促进清洁能源转型和生态保护的双重作用，是黄河流域生态保护和高质量发展的重要举措。 |

| Fully leveraging the benefits of water conservancy hub projects and thus facilitating high-level integration of wind and solar energy is of great significance for the high-quality development and ecological protection of the Yellow River Basin. The "Ji Zi Bend" area in the Yellow River Basin is rich in wind and solar resources, but the lack of necessary flexible dipactchable energy limits the integration of wind and solar energy within the region. Additionally, coal mining and thermal power plant operations impose significant threats on the regional ecosystem. Therefore, this study analyzes the key role of the Heishanxia hydropower plant (planned installed capacity of 2000 MW) in facilitating the integration of wind and solar energy in the "Ji Zi Bend" area. The results indicate that after adopting a general operation scheme, the Heishanxia hydropower plant with a pump and storage hydropower plant (planned installed capacity of 3000 MW), can dispatch wind and solar energy equivalent to 1.89 times of its own capacity (3716 MW of wind plant and 5760 MW of photovoltaic plant), and a more flexible operation scheme could further dispatch wind and solar energy equivalent to 2.02 times of its own capacity (4212 MW of wind plant and 5888 MW of photovoltaic plant), which generates 7.12% higher power generation benefits than that of generation operation scheme. Furthermore, this study uses an ecological hydrological effect assessment model of photovoltaic power stations to quantify that the construction of a 5888 MW photovoltaic power station relying on the Heishanxia hydropower plant, can significantly promote ecological protection in this region, with an annual increase in NPP of 18.31×108 g DM (which is equivalent to abate CO2 emission of 1093 t standard coal). In summary, the construction and operation of the Heishanxia hydropower plant will bring co-benefits of energy and ecology, greatly promoting the goals of ecological protection and high-quality development in the "Ji Zi Bend" area of the Yellow River Basin. |
