Özet:

 

Maintenance scheduling of generating units in  restructured power systems is a collaborative and interactive process  between independent system operators (ISOs) and generating companies  (GENCOs). The ISO should comply with GENCO maintenance preferences subject  to targeted system reliability levels. This process might be multistage  since the admission of all initial unit outage requests may threaten system  reliability. Hence, the ISO accepts some proposals and determines  alternatives for the remaining units. The GENCOs are then allowed to confirm  the alternatives or revise them. In this paper the ISO problem of generating  unit maintenance scheduling is tackled. The objective function is to  minimize the deviation of awarded schedule from the requested schedule, as  measured in MW weeks. A novel and effective optimization technique is  developed to solve the problem at hand. In the proposed methodology, risk  leveling and dynamic programming optimization algorithms are concurrently  utilized to lessen the computation burden and enhance the solution process.  The effectiveness of the proposed method and its applicability to real-life  systems are verified by examining the generation section of the IEEE  reliability test system (IEEE-RTS). The performance of the new method is  also compared with that of the individual risk leveling approach.
