摘　　要：为提升电网消纳风电的能力,改善火电机组运行灵活性,本文基于压缩空气储能系统容量大、多能流耦合的特点提出了一种包含两台600 MW燃煤机组的风电-火电-压缩空气储能综合能源系统。首先通过构建系统热力学变工况模型,分析了关键参数对压缩空气储能系统性能的影响,然后以降低弃风率为目标,探究了综合能源系统在典型特征日的能流匹配和运行特性。结果表明,电能分配比由57.3%增加至76.0%时,储能系统输出热电比由0.84下降至0.30,对储能系统输出影响最为显著;典型特征日的仿真场景下,综合能源系统负荷调节能力强,能流匹配良好,弃风率仅为2.28%。通过上述分析,验证了所提出的系统具备可观的风电消纳潜力和运行灵活性。In order to improve the penetration rate of wind power and the operation flexibility of coal fired units,Based on the characteristics of large capacity and multi-energy flow coupling of compressed air energy storage system,this paper proposes a wind power-thermal power-compressed air energy storage integrated energy system including two 600 MW coal-fired units.Firstly,the influence of key parameters on the performance of the compressed air energy storage system was analyzed by establishing the thermodynamic model of the system,and then the energy flow matching and operation characteristics of the integrated energy system were explored with the minimum wind abandonment rate as the goal in a typical day.The results show that the output thermo-electric ratio of the energy storage system decreases from 0.84 to 0.30 with the energy distribution ratio increases from 57.3% to 76.0%,which has the most significant influence on the output of the energy storage system.Under the simulation scenario of a typical day,the integrated energy system has strong load regulation ability and good energy flow matching,and the wind power abandonment rate is only 2.28%.Through the above analysis,it is verified that the proposed system has considerable wind power consumption potential and operational flexibility.
