This paper presents a parallel in space algorithm for power system transient stability analysis suitable for implementations on message passing multiprocessors. A network partitioning scheme based on the subdivision of the factorization path tree of the network matrix is proposed and a parallel algorithm for solving sparse network matrix equations has been developed by arranging the matrix into a 'Bordered Blocked Diagonal Form' (BBDF). The parallelism in space transient stability analysis algorithm has been implemented on a message passing multiprocessor. Test results on a large power system are presented to show that the proposed algorithm can significantly speedup transient stability simulations.
