Abstract: Along with the high proportion of renewable energy integration and the penetration of large-scale power electronic devices, the supply structure of power systems, grid morphology, operation mechanism, and control basis have been profoundly changed. The scale and complexity of grid are unprecedented, posing new challenges for simulation technology. Real-time simulation of power systems is an important means to support the acceleration of large-scale power system simulation, to carry out hardware-in-the-loop tests of control and protection equipment, and to promote the transformation of power system digital intelligence, thus real-time simulation has received more and more attention in recent years. In this paper, we first sort out the new demands for new-type power systems in the aspects of real-time simulation step size, scale, etc. Then, comparing ten mainstream commercial real-time simulation platforms, we discuss the technical status of domestic and foreign platforms in terms of real-time strategy, hardware architecture, efficient algorithms, and simulation software in detail. Thirdly, the research progress of real-time simulation platform technology solutions is summarized around typical scenarios in new-type power systems. Finally, the future development direction of the real-time simulation platform from the perspective of the new-type power systems is summarized.
