数字孪生与信息物理系统在智能配用电的应用辨析

Application distinguish of digital twin and cyber-physical systems in smart power distribution and utilization

数字孪生(digital twin,DT)和信息物理系统(cyber-physical systems,CPS)都是电网数字化转型的关键技术,可以实现虚拟世界与物理世界的互动和融合,“双碳”目标背景下,为解决可再生能源大规模接入电网带来的电力系统安全与经济运行的技术瓶颈提供了有效手段。然而,两者在很多方面有交叉,在实际应用中容易引起歧义。从DT与CPS的内涵及相互联系、信息物理耦合机理与融合建模、数字孪生应用场景等几个方面进行阐述与分析,并对DT与CPS技术在配用电领域应用的难点与技术发展趋势进行展望。

Digital twin(DT)and cyber-physical systems(CPS)are key technologies in the digital transformation of power grids.They allow for the interaction and fusion of the virtual and physical worlds,and are effective means of addressing the technical bottlenecks in power system safety and economic operation brought by the large-scale integration of renewable energy in the“dual carbon”context.However,there is a lot of overlap between the two technologies in many aspects,which can easily cause ambiguity in practical applications.This paper will elaborate and analyze the connotations and interconnections of DT and CPS,the coupling mechanism of cyber and physical and integrated modeling,and several application scenarios of digital twins.It also discusses the challenges and future development trends of DT and CPS technology in the field of distribution and utilization of electricity.
