Overview and Prospect of Real Time Simulation Platforms for New-type Power System
Along with the high proportion of renewable energy integration and the penetration of large-scale power elec-tronic 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 technol-ogy.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.
