This paper presents a practical and efficient method for long-term generating maintenance scheduling with various constraints for the deregulated power system. Using the Benders Decomposition, an approach has been developed for the long-term maintenance scheduling of generating units. This approach is efficient because a solution is obtained usually within a few iterations. The resulting long-term generation maintenance scheduling provides the time intervals, for a one year planning horizon, when generating units in a GENCO is taken off-line for planned preventive maintenance. The algorithm minimizes the total operating cost for a GENCO. Since in a competitive deregulated environment, both GENCO and ISO (Independent System Operator) are operated independently of each other, we apply Benders Decomposition to include the ISO’s constraints in the long-term generating maintenance-scheduling problem to meet the energy demands, reliability and other system requirements.
