除了碳计量理论方面的完善外,推进碳计量标准装置的落地也是构建电力系统碳计量体系的重要环节。碳计量装置为间接碳排放的可测量、可报告、可核查提供支撑。然而现有的中心化碳表系统难以满足多电压等级的全环节碳计量。因此,该文提出一种用于计算电力系统碳排放流的分布式碳表系统。首先,分别从感知层、网络层和应用层介绍了分布式碳表系统的物联网架构。在此基础上,构建了分布式碳表系统的通信网络,给出了2种分布式碳表系统计及网损的计量方式,考虑实际应用提出了分布式碳表系统的关键技术。为验证系统有效性,基于我国某地市的电力系统开展实验与分析,结果表明分布式碳表系统实现了电力系统全环节间接碳排放的本地实时、精确计量。最后,分别从源网荷储的角度对未来支撑电力系统碳计量体系和标准的关键技术进行了展望。

In addition to the improvement of the carbon metering theory,promoting the landing of the carbon metering standard devices is also an important component in building a carbon metering system in the power system.The carbon metering devices make the indirect carbon emissions measurable,reportable and verifiable.However,the existing centralized carbon metering system may not meet the requirements of the multi-voltage level carbon metering throughout the entire power system link.Therefore,this paper presents a distributed carbon meter system for calculating the carbon emission flow of the power system.Firstly,the IoT architecture of a distributed carbon meter system is introduced from the sensing,the network and the application layers respectively.On this basis,the communication network of the distributed carbon meter system is constructed,and two metering methods in the distributed carbon meter system considering the network loss are given,and the key technology of the distributed carbon meter system is proposed for its practical application.To verify the effectiveness of the system,experiments and analysis are carried out based on the power system of a city in China.The results show that the distributed carbon meter system achieves the local real-time and accurate metering of the indirect carbon emissions throughout the entire power system link.Finally,the key technologies to underpin the future carbon metering systems and standards in a power system are prospected from the perspective of source,network,load,and storage.
