Previous issue date: 2015-12-04 / Redes inteligentes representam um novo conceito de distribui??o de energia el?trica, que s?o o futuro dos sistemas atuais. Essas redes t?m sido introduzidas com o objetivo de aumentar a confiabilidade dos sistemas, prover alternativas para o suprimento de energia e reduzir custos. O aumento da complexidade das redes de energia, a crescente demanda e a introdu??o de fontes renov?veis de gera??o de energia, requerem uma integra??o e opera??o de todos os componentes do sistema, a fim de garantir altos ?ndices de confiabilidade e disponibilidade (dependabilidade). A sistematiza??o das redes inteligentes a partir do formalismo matem?tico de ?rvores de Falhas possibilita a analise quantitativa de tais ?ndices. Nesse trabalho ? proposto uma metodologia para an?lise da dependabilidade de redes inteligentes no contexto de distribui??o de energia el?trica. Um estudo de caso ? proposto para validar a proposta. A partir da metodologia ? poss?vel estimar ainda na fase de projeto a confiabilidade, disponibilidade e identificar os pontos cr?ticos da rede atrav?s das distribui??es estoc?sticas das taxas de falhas e reparos dos componentes. / Smart Grids are a new trend of electric power distribution, the future of current systems.
These networks are continually being introduced in order to improve the reliability
of systems, providing alternatives to energy supply and cost savings. Faced with increasing
electric power grids complexity, the energy demand and the introduction of alternative
sources to energy generation, all components of system require a fully integration in
order to achieve high reliability and availability levels (dependability). The systematization
of a Smart Grid from the Fault Tree formalism enable the quantitative evaluation of
dependability of a specific scenario. In this work, a methodology for dependability evaluation
of Smart Grids is proposed. A study of case is described in order to validate the
proposal. With the use of this methodology, it is possible to estimate during the early design
phase the reliability, availability of Smart Grid beyond to identify the critical points
from the failure and repair distributions of components.
