| 摘 要： | 为准确分析压缩机、透平膨胀机、换热器等组件的部分负载特性对先进绝热压缩空气储能(AA-CAES)系统变工况运行性能的影响,详细分析了各组件的部分负载热力学特性及AA-CAES变工况特性。提出了包含储气库储气水平与高温储热罐储热水平的双荷电状态(SOC)模型。通过变工况特性曲线簇建立了储气SOC与储热SOC间的耦合关系,进而建立了计及组件部分负载特性的AA-CAES变工况运行模型,并对风储协同系统发电能力评估问题进行分析。仿真表明,AA-CAES变工况运行模式导致的组件部分负载特性对风储协同系统发电能力的影响不容忽视,与不考虑变工况相比,对风力资源丰富地区,变工况运行特性将使风储协同系统容量因子降低达4%以上。

| Abstract: | To investigate the impact of the part-load characteristics of internal components such as compressor, air turbine and heat exchanger on the off-design operation of advanced adiabatic compressed air energy storage(AA-CAES), detailed analysis on the part-load thermodynamics characteristic of each component and off-design operation of AA-CAES are performed. Dual state-of-charge(SOC)model is proposed including the gas storage level of the gas storage unit and the heat storage level of high-temperature thermal storage unit. With a set of off-design characteristic curves, coupling relationship between SOC of the thermal storage unit and SOC of the air storage unit is established. Thus an off-design operation model for the AA-CAES considering part-load characteristic of each component is established and estimation problem of wind power and energy storage hybrid system''s generation capicity is analyzed. The simulation results show that the impact of part-load characteristics of each component resulting from the off-design operation of AA-CAES on the generation capacity of wind power and energy storage hybrid system cannot be ignored. Compared with the situation of ignoring off-design conditions, the capacity factor could discount over 4% caused by the off-design characteristics in the wind-rich areas. |
