Composite systems operating reserve assessment using a reliability framework

Unit commitment analysis in composite generation and transmission systems is presented in this paper using a reliability approach designated as the well-being framework. Assessment of unit commitment in a composite system incorporates the ability of the transmission system to deliver the generated energy to the major load points. A contingency enumeration technique is used to determine the composite system well-being indices for a given number of committed units. The IEEE-Reliability Test System (IEEE-RTS) is used to illustrate the techniques and procedures presented in this paper.
