Probabilistic evaluation of the Brazilian interconnected power systems; Avaliacao probabilistica do desempenho do sistema interligado brasileiro

Abstract

This paper describes the main features of the NH{sub 2} model, developed for the probabilistic evaluation of the adequacy of large scale power systems. The system analysis is carried out through a full set of indicators, including reliability indices and probability distributions of selected variables, such as area interchanges, power flow in circuits, voltage in buses etc. These indicators are calculated in two stages: before and after the introduction of remedial actions. Also, the model yields the representation of system hourly load curve, with uncertainty around the load levels. The flexibility and performance of the NH2 model are illustrated in case studies with a 1400-bus, configuration of the Brazilian system. (author) 12 refs., 11 figs., 6 tabs.
