Sba Controle & Automação [online]. 2003, vol.14, n.3, pp.262-271. ISSN 0103-1759.  https://doi.org/10.1590/S0103-17592003000300005.

This paper presents a new methodology to evaluate the reliability of distribution systems considering the impact of failures from the generation and transmission (G&T) systems. Therefore, an integrated adequacy evaluation, including generation, transmission and distribution, is performed in order to provide a more detailed information about interruptions experienced by consumers. The G&T systems are represented by a fictitious equivalent network, whose parameters are obtained by Monte Carlo non-sequential simulation. The equivalent G&T network is then connected with the distribution network and analyzed by the minimal cut-set theory. Traditional distribution indices (e.g. SAIFI, SAIDI, etc.) as well as the LOLC - Loss of Load Cost - indices are disaggregated to measure the contribution of G&T and distribution systems on the overall system indices. The proposed method is applied to the IEEE-RTS, which represents the G&T system, connected with the RBTS, which represents the distribution system. The results and their potential applications to the new power system competitive environment are discussed.

Palavras-chave : Distribution reliability; reliability worth; generation transmission and distribution reliability; hierarchical level 3.
