摘　　要：为缓解弃风问题带来的不利影响及提高风能的利用率,基于先进绝热压缩空气储能(Avanced Adiabatic Compressed Air Energy Storage,AA-CAES)技术,对输出功率为100 MW的蓄热式AA-CAES概念电站进行了初步设计,并对其进行了性能计算与经济性分析。性能计算结果表明,该电站年发电量约为1亿k W·h,弃风电量回收率约为62.64%,储能密度可达8.23 MJ/m3,蓄热效率为46.5%;经济性分析显示,该电站容量成本约为4,704.5元/k W;电站年运行成本约为4,402万元;电站年总效益可达27,232万元,年财务收益约2,573万元,年均利润率为2.34%。分析了储能购电价格变动对年运行费用及度电成本影响;得到了不同购电价格下,成本回收年限与释能电价的变化情况,为电站上网电价的定价提供参考。To alleviate the negative effects of wind curtailment and improve the utilization factor of wind energy,preliminary design of a 100MW conceptual regenerative AA-CAES power plant is made,based on the adiabatic advanced compressed air energy storage （AA-CAES） technology.On one hand,its performance parameters were calculated and economy was analysed.The results of performance calculations show that the annual generation capacity of the plant is about 100 million kW · h,the wind curtailment power recovery rate is about 62.64％,the energy density of the plant is 8.23MJ/m3,and the heat storage efficiency is 46.5％.The economic analysis indicates that the plant capacity cost is about 4,704.5 yuan/kW,the annual operating cost of the station is about 44.02 million yuan,the total benefit of the plant is about 272 million yuan,the financial income is 25.73 million yuan,the annual profit margin is 2.34％.On the other hand,the effects of various storage electric prices on the operation cost and per kW · h of electricity were analyzed.Under the conditions of different purchase prices,the relationship between recovery period and sale price was discussed,which can provide reference for feed-in tariff.
