摘　　要：随着全球气候变化对人类社会的影响日益加剧,实现碳达峰和碳中和目标已成为国际社会的共同责任。火电作为主要的碳排放源之一,其有序退役是推动能源结构转型、构建清洁低碳安全高效能源体系的关键步骤。高比例可再生能源和高比例电子设备的“双高”特性日益凸显,给系统带来频率安全方面问题。为此,在火电机组退役过程中考虑了系统的转动惯量需求。首先,建立了系统最小转动惯量需求模型和传统火电机组退役模型;然后,以IEEE 24节点系统为例,给出了机组退役和电源规划的结果;最后,从系统转动惯量的角度评估了模型的有效性。As the impact of global climate change on human society intensifies,achieving the dual carbon targets has become a shared responsibility of international community.Thermal power,as one of the main sources of carbon emissions,plays a key role in promoting the transformation of the energy structure and in building a clean,low-carbon,safe and efficient energy system through its orderly retirement.The“dual high”characteristics of a high proportion of renewable energy and a high proportion of electronic devices are becoming increasingly prominent,posing frequency security issues for the power system.To address this,the text considers the system s rotational inertia requirements during the retirement process of thermal power units.Firstly,the model for the retirement of traditional thermal power units and the minimum system inertia demand model are established.Then,taking the IEEE 24-node system as an example,the results of unit retirement and power source planning are provided.Finally,the effectiveness of the model is evaluated from the perspective of system rotational inertia.
