| Abstract: | Full-AC load flow is a crucial task in power
system analysis. Solving full-AC load flow utilizes iterative
numerical methods such as Jacobi, Gauss-Seidel or Newton-
Raphson. Newton-Raphson is currently the preferred
solver used in industrial applications such as Power World
and PSS/E due to it faster convergence than either Jacobi
or Gauss-Seidel. In this paper, we reexamine the Jacobi
method for use in a fully pipelined hardware implementation
using a Field Programmable Gate Array (FPGA) as
an alternative to Newton-Raphson. Using benchmark data
from representative power systems, we compare the operation
counts of Newton-Raphson software to the proposed
Jacobi FPGA hardware. Our studies show that
Jacobi method implemented in an FPGA for a sufficiently
large power system has the potential to be a state of the art
full-AC load flow engine. |
