| The reliability of the electric power system, defined as the degree of performance of the grid according to accepted standards, is composed of two components: (1) Security: The ability of the electric system to withstand sudden disturbances such as electric short circuits or unanticipated loss of system elements. (2) Adequacy: The ability of the electric system to supply the aggregate electrical demand and energy requirements of the customers at all times, taking into account scheduled and reasonably expected unscheduled outages of system elements.;There is evidence that the performance of the adequacy component of reliability is declining in North America. This research presents an improved set of metrics and a tool that supports an adequacy-monitoring model designed to track performance and identify underlying problems that impact reliability. |
