Node decomposition techniques for multiprocessing power system studies

Presents a novel method based on node tearing analysis for the solution of power system load flow problems. The technique is applied to the linearized real and reactive power models obtained in the fast decoupled load flow method. By considering node tearing as the reduction of subnetworks to multiterminal equivalents, sparsity and sparse network reduction techniques are widely used. Heuristic structural decomposition techniques are presented. The results of applying this methodology to standard test systems are illustrated and compared with a one-piece solution.
