摘要:

水电具有来源清洁、运行成本低等优点,科学合理地开发水电资源对于可持续发展意义重大,其中抽水蓄能电站还将充分发挥高效的储能优势,有助于提升电网运行的稳定性和可靠性。为了更好地开发利用有限的水电资源、克服地理条件等诸多限制因素,探讨了常蓄混合式水电站的开发型式,并以新疆玛纳斯河山区水电开发为例开展研究,基于已规划的3座蓄水式电站,提出了4种优化开发方案,根据水头和日调节蓄能库容等,调整发电洞压力管直径和水道断面积等以增加装机容量,水电资源的综合利用效益将得以显著提升。经研究表明,采用常蓄混合开发模式的水电站总装机最大容量和年总发电量将可以分别达到270万kW和60.12亿kW·h,相较于原定的水电梯级利用及规划开发方案分别增加了5.8倍和4倍,可消纳风、光及电网低谷电量57.24亿kW·h,将实现水资源高质量和高效益综合利用,为优化开发水电资源提供了新思路。

Abstract:

Hydropower has the advantages of clean and low-operation cost, and the reasonable development of hydropower resources is of great significance to promote the social sustainable development, specifically, the pumped-storage power stations will improve the stability and reliability of the power grid operation, as its distinct natures of efficient energy storage. However, the development of the traditionally pumped-storage power station is also restricted by many factors such as the geographical conditions. In order to better utilize the hydropower resources, this work explores a new pathway of the conventional and energy-storage hybrid hydropower concept, and takes the development of hydropower in the Manas River in Xinjiang as an example. Based on the planned three typical storage-type hydropower plants, four optimized development schemes are proposed. According to the waterhead and daily adjustment capacity of storage, the diameter of the pressure pipe of the power tunnel and the cross-sectional area of the waterway are increased to improve increase the plant hydropower capacity, the comprehensive utilization benefits of the hydropower resource will be evidently enhanced. Compared to the original development plan for the graded utilization of hydropower resource, the maximum installed capacity and total annual power generation of the energy-storage hybrid hydropower scenario will improve to 2.7 million kW and 6.012 billion kW·h, which are 3.9 times and 4 times higher than the original one, respectively. Moreover, this scenario is able to consume the surplus electricity of 5.724 billion kW·h of the solar/wind power or the off-peak power load, which will enhance the efficient utilization of hydropower resources. This positive method provides an alternative route for optimizing the exploration of hydropower resources.

Key words: hydropower generation, cascade utilization, conventional and energy-storage hybrid hydropower station, optimized utilization
