Power sector carbon emissions (PSCEs) have received an increasing attention due to their huge contribution to global greenhouse gas emissions. Herein, the research characteristics and trends of PSCEs are investigated based on bibliometric analysis. The basic growth trends, contributions of the most productive countries/territories, institutions, authors, journals, and subject categories are analyzed systematically. In addition, the major research fields and research trends are investigated by the keywords co-occurrence analysis and topic evolution. The result indicates that PSCEs research has developed rapidly in the past 20 years, and the proportion of research funding has increased from 0 at the beginning to 73% in the last 5 years. Especially, the number of scientific publications has shown an explosive growth after the signing of the Paris Agreement in 2016. The People's Republic of China (PR China), the USA, and England are the three most dynamic countries in the field of PSCEs research, with 64.8% of the total number of published papers. The most productive institutions are also from these countries. Based on keywords co-occurrence analysis, it is concluded that driving factors, prediction, impacts, and countermeasures of carbon emission are three major research fields. The result of thematic evolution indicates that the topics on energy transition, life cycle assessment, marginal abatement cost and energy policy have been the research hotspots in recent years. This study presents an worldwide overview of PSCEs research, thus helping the stakeholders to quickly grasp the research trends and conduct future work.
电力部门碳排放（PSCEs）因其对全球温室气体排放的巨大贡献而受到越来越多的关注。在此，基于文献计量分析对PSCEs的研究特征和趋势进行了调查。系统分析了其基本增长趋势、最具生产力的国家/地区、机构、作者、期刊和学科类别的贡献。此外，通过关键词共现分析和主题演化研究了主要研究领域和研究趋势。结果表明，PSCEs研究在过去20年中发展迅速，研究资金比例从最初的0增加到过去5年的73%。特别是，2016年《巴黎协定》签署后，科学出版物数量呈爆发式增长。中华人民共和国、美国和英国是PSCEs研究领域最具活力的三个国家，占发表论文总数的64.8%。最具生产力的机构也来自这些国家。基于关键词共现分析，得出碳排放的驱动因素、预测、影响和对策是三个主要研究领域。主题演化结果表明，能源转型、生命周期评估、边际减排成本和能源政策等主题近年来一直是研究热点。本研究对PSCEs研究进行了全球概述，有助于利益相关者快速掌握研究趋势并开展未来工作。
