| Summary: | Grid-forming static var generator (GFM-SVG) has the advantages of fast dynamic response, strong overload capacity, no delay, which is a new method to improve the voltage support capacity of the power grid in the power supply hollowing out. The engineering application of grid-type SVG is still in the initial stage worldwide, and there is a lack of effective technical methods to guide its application in multi-field under the new power system. As a new type of digital technology architecture, digital twin can provide a refined solution for the system perception, analysis and optimization of network-constructed SVG. To this end, combined with the practical application requirements, a digital twin system framework for the GFM-SVG is firstly constructed in this paper. Secondly, the key technologies to be broken through for the realization of the digital twin system framework are summarized from the perspectives of state perception, digital twin modeling, and data management. Finally, the full life cycle management and dynamic reactive power compensation are selected as typical applications, and the application method of digital twin in the GFM-SVG is prospected. |
