[Objective]Digital twin power grid is an important component of the new power system.Its current construction is confronted with problems such as diverse demand scenarios and insufficient coordination of technical routes.Therefore,a deeper analysis of the connotations underlying different application scenarios and strengthened systematic planning of the technical framework are essential.[Methods]Based on the summary of the practical experience of State Grid Corporation of China(SGCC)in recent years,this paper proposes the"five states"of digital twin power grids and interprets their connotations.From the perspective of different application scenarios,the construction requirements and key technologies of each state are discussed,and systematic construction frameworks are formed.[Results]The"planning state"of digital twin power grid strengthens the unification of the standard system throughout the full life cycle and the hierarchical construction of the model,which is the foundation for the construction of digital twin power grid.The"growth state"empowers power grid engineering construction,enhancing the quality and efficiency of three-dimensional design and construction.The"completed state"is oriented towards the digital transfer of power grid engineering achievements,strengthening the completeness of information and the consistency of diagrams and models.The"intelligent state"focuses on the intelligent management of equipment and enhances the intelligent perception capabilities of equipment and systems.The"emergency state"focuses on emergency repair of power grids,supporting the prevention and response to disasters such as ice,wind,lightning,line galloping,earthquake and fire.[Conclusions]The construction of digital twin power grid is a systematic project.It is not only the integrated application of technology but also the reconstruction of business processes and management models.
