With continually increasing complexities of power systems, transient stability analysis as an important task for system security operation becomes very time consuming and thus an efficient analysis tool is urgently needed. In this paper, a spatially paralleled hybrid approach combining the high-order Taylor series algorithm and the block bordered diagonal form (BBDF) was proposed to improve the computational efficiency of power system transient stability analysis. The proposed approach only exchanged high-order derivatives of generator voltages and currents between partitioned power network subsystems and the coordinated-bus cluster based on BBDF, and enhanced the triangular factorization recursive utilization rate of admittance matrix using the Taylor series algorithm with a large integration step. Finally, the proposed spatially paralleled hybrid approach was tested in the New England 39-bus, IEEE 145-bus and an expanded 580-bus systems, and simulation results have validated the proposed approach is very effective and computationally efficient for power system transient stability analysis.
