中文摘要：

采用低碳电力技术是电力行业实现可持续发展的重要举措。现有研究中,碳排放的统计量通常以宏观数据统计为主,按照一次能源消耗量转换得到。此类方法无法揭示电力系统碳排放的特点,在应用中存在着诸多局限性。文中探讨了将碳排放分析与电力系统潮流计算相结合的新思路,提出了电力系统碳排放流的概念。结合网络分析技术,提出并建立了电力系统碳排放流分析的几个基本概念与指标,初步形成电力系统碳排放流分析的理论架构。给出了一个示例系统的计算结果和直观展示,并结合电力系统潮流分析的基本原理,剖析了电力系统碳排放流分析理论的作用和意义。最后对电力系统碳排放流分析理论的应用领域和研究方向进行了展望。

英文摘要：

Low carbon electricity technology is an important measure for the sustainable development of power industry.According to the current research,carbon emission is usually calculated by official energy consumption statistics and convertion of primary energy consumption.This kind of methods cannot reveal the characteristics of carbon emission from power industry,and has many limitations in its application.As a new idea,the concept of the combination of carbon emission analysis and power flow analysis is investigated,and a new concept of carbon emission flow in power system is also proposed.By drawing on network analysis technique,several basic concepts and indices about carbon emission flow in power system are defined.Thus the theoretical framework for carbon emission flow in power system is preliminarily formed.Moreover,the carbon emission flow analysis results of an example system are shown intuitively,and the role and significance of carbon emission flow are discussed according to the fundamental principles of power flow analysis.Finally,prospects of application fields and new research trends of carbon emission flow in power system are given.
