摘　　要：综合能源系统(IES)灵活性可服务于高比例可再生能源下电力系统可调节能力的提升。然而,IES灵活性机理复杂、内涵丰富,尚缺乏统一认识与系统化阐述。首先,从灵活性导向的规划设计、运行调控、市场机制以及量化与评估方法等角度全面综述了电力系统灵活性和IES灵活性的国内外研究现状,并归纳分析了电力系统灵活性和IES灵活性的联系与区别。其次,指出了高比例可再生能源背景下研究IES灵活性的必要性,进而从定义、基本要素和测度体系等角度揭示了IES灵活性的基本内涵。然后,定义了IES灵活性数学模型的通用形式,并结合示例给出具体阐述。再次,从物理机理、提升途径以及建模、量化与评估方法3个方面构建了IES灵活性的研究框架。最后,总结展望了IES灵活性研究在内涵层面、机理层面和提升路径等方面的关键难题。Integrated energy system(IES)flexibility can serve the improvement of power system adjustability under high proportion of renewable energy.However,the mechanism of IES flexibility is complex and its connotation is rich,there is still lack of unified understanding and systematic elaboration.Firstly,the research status of power system flexibility and IES flexibility at home and abroad is comprehensively reviewed from the perspectives of flexibility-oriented planning and design,operation and regulation,market mechanism,and quantification and evaluation methods.The connection and difference between power system flexibility and IES flexibility are then summarized and analyzed.Secondly,the necessity of studying IES flexibility in the context of the high proportion of renewable energy is pointed out,and the basic connotation of IES flexibility is revealed from the perspectives of definition,basic elements,and measurement system.Thirdly,the general form of the mathematical model of IES flexibility is defined,and a specific elaboration is given with examples.Furthermore,the research framework of IES flexibility is constructed from three aspects:physical mechanism,enhancement approaches,modeling,quantification and evaluation methods.Finally,the key problems of IES flexibility research in terms of connotation,mechanism,and enhancement approaches are prospected.
