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.<>
