摘　　要：大规模新能源并网,增加了电力系统运行不确定性,新型电力系统在运行和规划过程中对灵活性的需求更为迫切。随着新能源并网比例增加,网络传输灵活性在系统灵活性供需中的限制作用更加显著。网络传输灵活性研究及其量化评估是保证系统灵活性资源的可用性,提升新型电力系统灵活性的关键。论文对电力系统网络传输灵活性及其评价研究进行评述和展望。首先,介绍电力系统网络传输灵活性的定义,并概况其特征为时序性、无方向性和固有性;其次,论述现阶段网络传输灵活性的研究场景及方法;再次,从网络可用输电容量、网络安全传输裕度及网络传输灵活性指标3方面,对现阶段网络传输灵活性评估指标进行梳理;最后,对电力系统网络传输灵活性的研究进行总结与展望。Due to the increasing uncertainties in power systems,the need for flexibility in the operation and planning of modern power systems is more urgent than ever.As the penetration of renewable energy sources increasing,the limit of network transmission flexibility in system flexibility supply and demand becomes more significant.The study of network transmission flexibility and its quantitative evaluation is the key to ensure the availability of flexible resources and to enhance the flexibility of power systems.This paper reviews and outlooks the research on power system network transmission flexibility and its evaluation.First,the definition of network transmission flexibility is introduced and its characteristics are outlined,including temporality,non-directionality,and inherency.Secondly,the research and methods of network transmission flexibility are discussed.Moreover,the assessment indexes of network transmission flexibility are sorted out from three aspects:network available transmission capacity,network safety transmission margin and network transmission flexibility index.Finally,the research on network transmission flexibility of power system is summarized and prospected,and then the issues that need attention in the research process are explained.
