The row-based iterative method was extended to the transient analysis of irregular power grid based on the efficiency in improving speed and reducing memory cost for regular power grid transient analysis.The system matrix was modified into a symmetric positive definite triangular matrix by making up the missing nodes in irregular power grid.Then the row-based iterative method can be applied to the system.Experimental results show that the row-based iterative method outperforms conjugate gradient method and random walk based method in speed and memory cost with guaranteed accuracy.
