Tool for evaluation of generating system reliability and its applications

Reliability is one of the most important criteria which must be taken into consideration during planning and operation phases of a power system even (or may be, particularly) in the time of disintegration, deregulation and competition. This paper considers the assessment of generating capacity reliability, in terms of adequacy; computationally efficient algorithms and theirs computer realization (GRA program). The GRA (generating reliability assessment) computer program main features are listed. The paper illustrates the utilization of the GRA program in Polish power system studies.
