| 摘要: |
| 依据燃气蒸汽联合循环（CCGT）机组的模式模型与组件模型，提出既降低变量维数又可快捷计算各元件出力的CCGT双层模型。构建CCGT参与消纳风电对系统运行成本、机组容量利用率与重爬坡持续时间、切负荷持续时间、风电利用率等系统安全经济运行指标影响的分析模型，并采用混合整数规划法求解。算例分析结果表明，单纯追求过大的风电注入量会引起系统运行指标趋坏，引入CCGT能显著提高系统的可靠性和经济性运行指标。 |

| Abstract: |
| A bi-level CCGT（Combined Cycle Gas Turbine） model is built based on its mode and component models，which may decrease the variable dimension and compute the output of each unit quickly. An analysis model is built and solved by the mixed integer programming method，which analyzes the influence of CCGT participating in the wind power absorption on the indexes of system safe and economic operation，such as system operating cost，unit capacity utilization rate，re-climbing lasting time，load shedding lasting time，wind power utilization rate，etc. Results of case analysis show that，the simple pursuance of large wind power integration will spoil the system operational indexes while the introduction of CCGT may improve them significantly. |
