APPLICATION OF CHRONOLOGICAL LOAD MODELING IN COMPOSITE RELIABILITY WORTH EVALUATION

This work describes the application of pseudo-sequential Monte Carlo s imulation to the composite generation-transmission reliability evaluat ion of the Brazilian South-Southeast system using chronological load m odeling. The resulting reliability indices, in particular the loss of load cost (LOLC), were compared with those produced by a sequential Mo nte Carlo scheme with chronological load model and by a non-sequential Monte Carlo simulation scheme using a multistate Markov load model. I t is shown that the pseudo-sequential approach produced the same indic es as the sequential approach, with a substantial reduction of computa tional effort. Those results were in turn quite different from the non -sequential Monte Carlo scheme, thus confirming the importance of an a ccurate load modeling. (C) 1997 Elsevier Science S.A.
