Abstract

In this paper the mean first passage time of a dynamic system from its domain of attraction has been considered as a reliability index. The effect of environmental fluctuations and the operational characteristics of the transmission lines have been regarded as the input noise to the system with multistable states. Several design criteria have been examined in order to determine the effect of system configuration on power system reliability evaluation. The proposed technique does not set any restrictions on the system topology and can be implemented by system planners as an aid to identify the transmission system bottlenecks and compare different options in the planning of a large-scale power system.
