Generator maintenance scheduling to maximize reliability and revenue

In this paper, attention is focused on measuring the impact of generating maintenance strategies on the system reliability and on the associated costs. The paper describes a maintenance model that captures accurately the beginning and the end of all maintenance scheduling requests. Specific situations involving maintenance and repair outages are considered. In order to measure the performance of a given maintenance request, a strategy based on incremental costs has been proposed. These costs account for variations in production, revenues and reliability caused by maintenance schedules. Several numerical examples, using a modification of the IEEE Reliability Test System, are presented and the corresponding results are analyzed in detail.
