Digital Twin for Power System Steady-state Modelling, Simulation, and Analysis

PSDT (Digital twin of power systems) is a promising medium to exploit the bonus of a stream of state-of-the-art technologies in smart grid. This paper first reviews the PSDT and its framework as the background. Then we focus on its fundamental applying scenario-PSDT-based modelling, simulation, and analysis (PMSA) for the steady-state, which is a supplement to and more adaptive than its conventional model-based counterpart. The PMSA is designed under the proposed PSDT framework, and validated using numerous cases. PMSA, aiming at a revisit of steady-state analysis of power system in today's escience age, may make a profound impact on the energy system, the energy internet, and the data science.
