Abstract: 

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.
