| Abstract(in English) | Because of its extremely large size, power grid analysis has been a computationally challenging problem both in terms of runtime and memory usage. LU factorization has been widely used to analyze voltage drop simulations due to its stability, but contiguous technology scaling demands even more efficient calculation methods. In this paper, application of block-iterative method, which combines LU factorization and iterative method, is proposed for efficient analysis of power grid analysis. Automatic adjustment of relaxation factor in successive over-relaxation method and block decomposition algorithm are proposed. Evaluation results are also presented. |
