Aging reliability model for generation adequacy

Abstract:

As time passes through, components tend to be less reliable because they suffer a degradation produced by aging. Focusing on reliability assessment for generation adequacy, generator reliability model hardly considers this fact. This assumption produces an inaccurate reliability assessment. This paper proposes a novel mathematical formulation that considers aging effect and brings estimation for the degradation of the component. The method is derived from the concept of absorption Markov chain to model component's lifetime. The specific contribution of this work is to present a comprehensive reliability model for generation adequacy.
