The Parallel Implementation of the Waveform Relaxation Method for the Simulation of Structure - Preserved Power Systems

In this paper, several results pertaining to the partitioning of the waveform relaxation algorithm for dynamic simulation are presented. The WR algorithm is extended to a structurepreserving power system model in which the loads are retained. This results in a system of differential/algebraic equations (DAEs). Power systems are shown to exhibit several dynamic characteristics which make them suitable for simulation by the WFL method. One of the main contributions of this paper is a heuristic method for determining a fault-dependent partitioning of the power system for parallel implementation.
