Abstract
Partial refactorization methods update the LDU factors of a matrix to reflect changes In some Its elements. This paper presents two new partial refactorization methods for sparse matrices. Test results Indicate that they are significantly more efficient than existing techniques, and have the potential to speed up a number of important power system problems.Keywords
