Preconditioner-Based Acceleration Method for Solving EMTP Linear Equations
Qi Lou, Yijun Xu, Yang Cao, Wei Gu, Fei Zhang
The computational speed of electromagnetic transient programs (EMTP) is severely limited by both the curse of dimensionality and the ill-conditioned system matrix, which collectively degrade solver performance. However, existing research on EMTP acceleration has largely overlooke…
