【摘要】：随着常规化石能源的日益枯竭和环境问题的不断突显,风能等可再生能源越来越受到人们的关注。近几年,风电发电技术的逐渐提高,降低了风电发电的成本,为风力发电的大规模发展提供了可能性。但风能资源受到自然环境的影响,导致风出力具有很强的随机性、间歇性和不可控性,大规模风电并网会对电力系统产生很大的冲击,因此,风电并网一直以来困扰着国内外风电场大规模的发展。风电场与抽水蓄能电站的联合运行,可以将不可控的风电转化为可靠性电源,有效降低风电对电网的影响。抽水蓄能电站作为电力系统中的一种特殊电源,通过抽水工况和发电工况,在系统中既可作为电源又能作为负荷,把风电场输出的功率进行“时间”和“空间”上的再分配,以实现更多的风力发电并网。在风力发电、光伏发电等新兴能源快速发展,多种能源并存的新形势下,实施多能互补,也是发挥多种能源各自优势,取长补短的重要措施。本文以“新疆艾比湖多能互补可再生能源基地规划”课题为应用背景,按照中国“十二五”风电“规模性开发与分散开发相结合”的新能源发展战略要求,首先介绍了风电开发与抽水蓄能电站联合建设问题研究背景,分析了当前的国内外研究情况,研究了目前加快开发风电与抽水蓄能电站联合建设面临的问题。然后,对风电与抽水蓄能电站联合运行的相关原理进行了分析,阐述了进行风电开发与抽水蓄能电站联合建设的必要性与优势。最后,结合新疆艾比湖可再生能源建设基地的实际,进行实证分析,提出多能互补可再生能源建设方案,并分析风电开发与抽水蓄能电站联合建设的经济性与可行性。
[Abstract]:With the depletion of conventional fossil energy and environmental problems, more and more people pay attention to renewable energy such as wind energy. In recent years, with the gradual improvement of wind power generation technology, the cost of wind power generation has been reduced, which provides the possibility for large-scale development of wind power generation. However, wind energy resources are affected by natural environment, which leads to strong randomness, intermittent and uncontrollable wind output, and large-scale wind power grid connection will have a great impact on the power system. Wind power grid has been puzzling the large-scale development of wind farms at home and abroad. The combined operation of wind farm and pumped storage power station can transform uncontrollable wind power into a reliable power supply and effectively reduce the influence of wind power on the power grid. As a special power source in power system, pumped storage power station can redistribute the output power of wind farm in "time" and "space" through pumping and generating conditions, which can be used as both power supply and load in the system. In order to achieve more wind power grid. Under the new situation of the rapid development of wind power, photovoltaic power and other new energy sources and the coexistence of many kinds of energy, it is also an important measure to give full play to the respective advantages of various energy sources and make up for each other's weaknesses. In this paper, based on the application background of "Planning of Xinjiang Ebinur Lake Multi-energy complementary Renewable Energy Base", according to the new energy development strategy requirements of China's "12th Five-Year Plan" wind power "scale development and decentralized development", This paper first introduces the research background of wind power development and the joint construction of pumped storage power station, analyzes the current research situation at home and abroad, and studies the problems faced by speeding up the development of wind power and pumped storage power station. Then, the related principles of wind power and pumped storage power station combined operation are analyzed, and the necessity and advantages of wind power development and pumped storage power station joint construction are expounded. Finally, combining with the reality of the construction base of renewable energy in Ebinur Lake, Xinjiang, this paper makes an empirical analysis, puts forward the construction scheme of renewable energy with multi-energy complementary, and analyzes the economy and feasibility of the combined construction of wind power development and pumped storage power station.
