Abstract (EN): In this paper a combined Monte Carlo-Hybrid Transient Stability approach for the dynamic security analysis of a multimachine power system is proposed. This approach evaluates a probabilistic measure of the transient stability, instead of just a particular response to a specified disturbance. Due to the large number of simulations required, the application of a hybrid method to assess transient stability reduces drastically the computing time. A probabilistic version of the software package TRANsySTEM, developed by the authors to study the transient security of a multimachine system, was applied to a test power network. During the simulation time, the occurrence of disturbances and the subsequent protective actions are assumed as a stochastic process. Finally, the obtained results are discussed and some conclusions that provide a valuable contribution to the understanding of the system dynamics are pointed out. © 2001 IEEE.
