Abstract

This letter presents the latest improvements of a previously proposed parallel and multistep approach based on the functional mock-up interface standard for the simulation of electromagnetic transients. The improved approach extends the capacity of the original parallel asynchronous mode into accommodating the use of different time-steps in different decoupled subsystems. It also introduces a signal correction procedure using linear extrapolation in multistep simulations, greatly enhancing simulation flexibility, efficiency, and accuracy. Numerical examples are provided to demonstrate the computational advantages of the improved approach.
