摘要： 内蒙古自治区陆上风能资源总储量达到了1380 GW,其中技术可开发量为380 GW,几乎占全国风电资源的一半.风力发电负荷已经占到内蒙古电网负荷的20%以上.针对这种情况,对大规模风电并入内蒙古电网进行了研究.在此研究基础之上,为了更有效的利用风电资源,设计了一台压缩空气储能电站.该压缩空气储能电站可以利用风电场夜晚的弃风电量进行储热,为白天的运行提供部分热源.最后,从热耗率,充电比与发电效率三方面对压缩空气储能电站进行了分析,研究结果表明,更高的储气压力和更大的储气容量能够得到更好的发电效率.

Abstract: The overall wind energy resources in Inner Mongolia is estimated at 1380 GW of which 380 GW can be actually explored. This accounts for 50% of total amount in China. Currently, over 20% of the electrical network capacity in Inner Mongolia is from wind power generation. This study concerns grid integration of large-scale wind power generation into Inner Mongolia power grid. A compressed air energy storage (CAES) system is designed in this work for effective and efficient utilization of the wind power. The CAES system harnesses the abandoned wind power at off peak hours (night) to produce high temperature heat for use on daytime. The effects of heat consumption, charge ratio and efficiency of CAES power recovery on the plant performance are investigated. It is found that high operating pressures and large compressed air storage capacities give high efficiencies of CAES system.

Key words: wind power, compressed air, heat storage, efficiency
