COMPARATIVE STUDY OF THREE LINEAR SYSTEM SOLVER APPLIED TO FAST DECOUPLED LOAD FLOW METHOD FOR CONTINGENCY ANALYSIS
Abstract: This paper presents
the assessment of fast decoupled load flow computation using three linear system
solver scheme. The full matrix version of the fast decoupled load flow based on
XB methods used in this study. The numerical investigations are carried out on
the small and large test systems. The execution time of small system such as
IEEE 14, 30, and 57 are very fast, therefore the computation time can not be
compared for these cases. Another cases IEEE 118, 300 and TNB 664 produced
significant execution speedup. The superLU factorization sparse matrix solver
has best performance and speedup of load flow solution as well as in contigency
analysis. The invers full matrix solver can solved only for IEEE 118 bus test
system in 3.715 second and for another cases take too long time. However for
superLU factorization linear solver can solved all of test system in 7.832
second for a largest of test system. Therefore the superLU factorization linear
solver can be a viable alternative applied in contingency analysis.
