Review of Methods to Accelerate Electromagnetic Transient Simulation of Power Systems [PDF]

IEEE Access, 2021
Converter-based generators are increasingly replacing classical synchronous generation, resulting in significant challenges to the operation and planning of modern power systems. Power electronics (PE)-based equipment, along with non-linear PE-driven loads, introduce time-varying characteristics and fast switching behavior that increases the complexity
