Abstract: | This paper presents a modified four-state model that can be utilized to assess adequacy at the generation level of a power system. The model can incorporate various operating factors that influence system reliability. A new probabilistic technique that utilizes the model has been developed to evaluate static reserve capacity and margin in a generating system for a given risk criterion. The model can also be utilized in adequacy assessments with deterministic approaches. © 1998 John Wiley & Sons, Ltd. |
