Real-time dynamics simulation of large-scale power systems is a computational challenge due to the need of solving a large set of stiff nonlinear differential-algebraic equations. The main bottleneck in these simulations is the solution of the linear system during each nonlinear iteration of the Newton's method. We present a parallel linear solution scheme using Krylov subspace based iterative solver GMRES with a Block-Jacobi preconditioner that shows promising prospect of a realtime dynamics
