Indirect methods have been eschewed for use on serial processors by the power industry but may be competitive with direct methods for utilizing large scale parallel processors if the number of precedence relationships experienced by both direct and indirect methods are comparable. A new highly parallel truncated accelerated Neumann series preconditioner is presented. Results from using this preconditioner with a Jacobi-like iterative scheme on a 118 and 494 bus system are presented. These results show that the number of precedence relationships experienced by this technique are of the same order of magnitude as the number encountered when using direct methods.
