Key Technologies and Prospects for Electromagnetic Transient Parallel Simulation in New Power Systems
Driven by the strategic goals of"peak carbon emissions"and"carbon neutrality",power system is transforming into a new power system marked by extensive integration of new energy sources and a significant presence of power elec-tronic devices.This transformation induces significant changes in its power source structure,and operational characteristics.Electromagnetic transient simulation,possessing the capability to comprehensively and precisely depict the high-frequency dynamic traits of the power system,has become a pivotal tool for understanding the operational fea-tures of the new power system.However,electromagnetic transient simulation techniques under the traditional serial computing mode is inadequate in addressing the simulation scenarios involving the large-scale integration of new energy sources and the complex coupling of AC and DC systems.Urgent research is needed to explore efficient parallel algo-rithms and hardware acceleration perspectives for electromagnetic transient simulation in a parallel computing mode.To this end,this paper first outlines the new demands of the new power system for electromagnetic transient simulation.It then introduces parallel algorithms for electromagnetic transient simulation,followed by a presentation of multi-rate sim-ulation methods to further enhance efficiency,and introduces parallel simulation implementation schemes based on parallel computing devices.Finally,it reviews the parallel strategies of electromagnetic transient simulation platforms domestically and internationally,concludes that a simulation platform with deep integration of algorithm and hardware is the future direction,and also provides an analysis and outlook on key technologies involved.
