摘要(Abstract):

风能、太阳能等可再生能源的非稳定输出特性对电网系统的安全运行影响很大。储能系统不仅可以调节电网负荷提高供电品质,而且可以作为应急电源。本文对不同储能方式进行了分析,研究了储存压力和流量等运行参数对微小型压缩空气储能系统输出功率与运行效率的影响,提出了风电单元配置微小型压缩空气储能系统的调控方案和需解决的关键技术,对储能系统发展和提高电网安全运行有参考意义。
The unsteady output characteristics of renewable energy such as solar and wind energies have large effect on the safety of electric grid. The application of energy storage system not only can regulate electric grid load and improve power generation quality,but also can be used as an emergency electric source. The different ways of energy storage are analyzed. The effect of storage pressure and flow rate of compressor and expander on output power and efficiency of small scale compressed air energy storage system( CAES) are researched. It is put forward that each single wind power apparatus is equipped with a small CAES, and relative key technologies are pointed out. The paper is significant to the development of energy storage system and safety of electric grid.
