Operating considerations in reliability modeling of interconnected systems-an analytical approach

The authors present an analytical method which can incorporate both operating considerations and interconnection constraints in multiarea reliability evaluation. The model, called OPRINS, is a substantial extension and generalization of concepts contained in a single-area OPCON model and the decomposition-simulation approach for multiarea reliability evaluation. These techniques have been implemented in two computer programs called OPRINS-A and OPRINS-P for the study of interconnected systems operating in 'area' or 'pool' modes for commitment of generating units. Some system studies are described which compare the results obtained from this approach with the comparative sequential simulation models.>
