摘要：

The effect of steady and transient state responses of a power system on its performance evaluation has been investigated. Retention of all buses from the original power system has been noteworthy along with the modelling of frequency dependent load buses. Inputs to the system are regarded as small perturbations in operational characteristics of transmission lines and system loads. This type of perturbation is modelled by a Gaussian stationary process with constant spectral density. The mean first passage time of a dynamic system from its domain of attraction has been considered the performance index. The sensitivity of this index to the variation of different system parameters has been investigated, and several design criteria have been examined to determine the effect of system configuration on power system performance evaluation.
