Vector implementations of fast decoupled and Gauss-Seidel load flows

摘要

Several vector implementations of fast decoupled load flow and Gauss-Seidel load flow are presented in this paper. Vectorized direct (W-matrix) and iterative (preconditioned conjugate gradient) methods are used to solve the linear equations of fast decoupled load flow. A vectorization scheme for the Gauss-Seidel load flow method has also been developed. Comparisons of these methods using Alliant FX/80 and Convex 3840 computers are reported.
