The management of transformers’ capacity is a vital task for planners and asset managers due to their high cost. This paper proposes an optimization model for capacity management of transformers in a substation over long-run. The model considers the present worth costs of investment, losses, maintenance, reliability, and the salvage value of transformers for providing the optimal selection and scheduling...
Traditionally, reliability evaluations for substation configurations and distribution networks are performed separately and substation reliability evaluation only focuses on a single substation. This paper presents a technique to assess the reliability of multiple substations with associated distribution networks. Based on Markov modeling, a clustering approach, a linear programming algorithm and...
The paper discusses the modeling of substations for reliability, dealing with each equipment and its influence in the topology. The study consider the power availability for each load, using either an analytic and a simulation model. Some results and a software implementation are presented.
