Iterative Multistep Methods for Transient Stability Studies

Multistep integration algorithms suitable for transient stability studies are developed by combining conventional, implicit multistep formulas with new iterative procedures. A simple power system example is used to compare the performance of the multistep algorithms to that of a fourth-order Runge-Kutta method. The results of this preliminary experimental investigation indicate that for comparable accuracy, the multistep algorithms require significantly less computing effort.
