Abstract :
Traditionally, the need for system reinforcements to improve customer supply reliability has been determined solely based on deterministic criteria. For example, the widely used single contingency criterion (N-1 criterion) requires that acceptable system conditions shall exist after the loss of a major system equipment such as a generating unit, transmission line or transformer. Though easy to use, due to inherent limitations, the deterministic criteria can not realistically model the stochastic nature of power system behavior. Probability based models have been developed to accurately reflect stochastic nature of a power system behavior and assess its reliability performance. This paper presents different features of such a reliability model used to compute the reliability performance of a practical transmission system
