Abstract:
In a centralized power system, the system operator, derives a maintenance scheduling plan that maximizing reliability of system and minimizing operating cost. But in a restructured power system the goals of GENCOs and independent system operator (ISO) are separate and each of them optimize its own goal. The goal of each GENCO is to maximize its annual benefits and the goal of ISO is to maximize the reliability of system throughout the year. Therefore there are two objective functions for finding an optimum maintenance schedule in restructured power system. This thesis proposes a new method for maintenance scheduling of generation units in a restructured power system. Firstly each GENCO determine the maintenance schedule of its units then the ISO compares its reliability index with reliability index related to maintenance scheduling of GENCOs. If they are close enough in term of reliability, it will be approved; otherwise ISO sets up incentive and disincentive factors for all day of the year to encourage GENCOs to modify their maintenance schedules
