This paper presents a new probabilistic methodology for sizing the number of spare transformers for a group of power distribution substations. Based on a chronological Monte Carlo simulation, the proposed methodology allows the assessment of several reliability indices and expected costs, even considering systems composed by transformers with different ages and non-exponential lifetimes. Real conditions...
This paper proposes a new probabilistic method based on chronological Monte Carlo simulation for computing optimal distribution substation spare transformers. The method allows the representation of events such as aging process, load growth, and other conditions not supported by traditional methods based on Poisson and Markov processes. The lifetimes of the transformers are represented by discrete...
