平抑风电出力波动储能技术比较及分析

风电出力波动影响到其利用效率及电网安全,若利用储能设备可以减轻风电出力波动的影响。开展不同储能技术的特性和效能研究,目的是找到可用的平抑风电出力波动的设备。收集并研究了现有技术下储能设备的技术参数,并对其接入电网的方式、效能及规模效应等方面进行分析和技术经济对比。经过大量的数据分析,借助其他相关课题的研究成果,发现电网是唯一可聚集巨大调节能力的储能系统,也是目前最有效、最经济的储能系统。最终论证了中国减轻能源行业污染、增强能源安全,应该大规模开发三北的风电,而建设大电网才是我国开发大风电的出路。

Comparison and analysis of energy storage technology to balance fluctuation of wind power output

Wind power output fluctuation affects its efficiency and power system security. Using energy storage device can reduce the influence of the wind power output fluctuation. The characteristics and efficiency of different energy storage technologies are researched in order to find the available devices for stabilizing wind power output fluctuation. This paper collects and studies various technical parameters of existing energy storage devices, and makes technical and economic comparison of the methods connected to the grid, functions and scale effect. By use of a lot of data analysis and the findings of other related topics, this paper finds out that power grid is the only energy storage system can gather a huge ability of regulate, which is currently the most effective and economical energy storage system. Ultimately it proves that China should develop wind power in the three-north region on a large scale to reduce pollution in energy industry and enhance energy security, while the construction of large power grid is the way of the development of wind power in China.
