Quantitative evaluation of power system reliability in planning stage is one of the effective approaches to realize more efficient facility investments. Especially, recent movements toward more effective utilization of existing facilities calls for precise evaluation of appropriate time of investments, and in this respect, reliability analysis based on a probabilistic method is expected to play an important role as one of the powerful planning tools.<br> This paper discusses reliability analysis of the specific portion of a trunk transmission network, which supplies bulk power to the metropolitan area. The sequential Monte Carlo method is applied in order to evaluate the effect of yearly demand profile and operation strategies on power system reliability.<br> Application of the developed tool to a model network revealed that the transfer capability of existing transformers may be increased in probabilistic sense without significant deterioration of reliability, indicating the possibility of investment deferral.<br> In this paper, effects of applying new short time overload rating on transmission facilities are also examined. Initial short time overload rating on transformers is adopted, which allows more overloads on transformers than conventional rating for relatively short period just after the faults. The reliability analysis showed that this new rating can decrease the opportunities of loss-of-load, and as a consequence, can be effective in improving probabilistic transfer capability of the transformer.
