Abstract (EN): In this paper a combined Monte Carlo-extended equal area formulation for the transient security assessment 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 calculations required, the application of the extended equal area criteria reduces drastically the computing time, since it allows to evaluate the critical clearing times and the stability margins without solving numerically the differential motion equations. The probabilistic software package TRANsySTEM, developed by the authors to study the transient security of a multimachine system, is applied to a test 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.
