Power Grid Digital Twin Platform and Application in Power Dispatching

With the continuous expansion of power grid, the interaction between UHVAC and DC lines and between large regional power grids is further strengthened, and the renewable energy integration is greatly increased. These situations pose severe challenges to real-time, flexible and agile decision support for current power dispatching business. In this paper, the development of digital twin in power system is investigated in detail. Then the power grid digital twin virtual model, which can provide real-time online physical model, real-time power flow section and calculation model services is constructed and the digital twin platform for power dispatching is established, which can support the new online analysis system with faster response speed. Finally, two specific power dispatching applications using power grid digital twin platform is discussed.
