摘　　要：压缩空气储能(CAES)是一项清洁的储能技术,其接入电力系统在为实现高比例可再生能源消纳提供一种新的解决途径的同时,也会对发输电系统可靠性评估产生影响。首先,运用马尔可夫方法对CAES建立了通用的故障概率模型,并且该模型能够考虑储气容器损坏的情形;其次,针对该模型提出了能反映储能侧能量损失的系统指标,并探讨了CAES的不同控制参数对发输电系统指标的影响;接着,在修改后的IEEE RTS-79系统中利用灵敏度分析方法来识别影响CAES中的组合模块、整体装置和发输电系统指标的关键元件,并结合经典二分法理论来挖掘CAES并网的容量价值;最后,探讨了风电场与CAES协调配合对系统可靠性的影响,评估结果可为CAES的设计及配置方案提供有益的参考。Compressed air energy storage(CAES)is a kind of clean energy storage technology.The integration of CAES into the power system provides a new solution for achieving accommodation of high proportion of renewable energy,and it has an impact on the reliability evaluation of the power generation and transmission system.First,the Markov method is used to establish a general failure probability model for CAES,and the model can consider the damage of air storage container.Secondly,a system index that can reflect the energy leakage on the energy storage side is proposed for this model,and the impacts of different control parameters of CAES on the indices of the power generation and transmission system are discussed.Then,the sensitivity analysis method is used to identify its key components,which affects the indices of the combination module,device of CAES and power generation and transmission system in the modified IEEE RTS-79 system.And it can be combined with the classical dichotomy theory to quantify the capacity credit of CAES integration.Finally,the influence of wind farm and CAES coordination on the system reliability is discussed.The evaluation results can provide useful reference for the design and configuration scheme of CAES.
