Research On Theory And Practice Of Maintenance Scheduling For Generating Units In Electricity Market Environment

Electric power market has begun, the Generation Companies must improve itscompetence by decreasing cost and increasing profit .The revenue of a generationcompany depends on its energy supply as well as the market price. Building a reasonablemaintenance scheduling has become one of the most important strategies or generationcompanies to maximize profits. The traditional approach of generation maintenancescheduling employed by the system operator through a centralized optimization methodis no longer acceptable. Given this background, a optimal strategies of maintenancescheduling with risk well taken into account is developed, and based on the chanceconstrained programming a new methodological framework and a mechanism ofadjustment are developed.At last ,the paper studies a software about optimal strategiesof maintenance scheduling based on the DELPHI and the model of optimal strategies ofmaintenance scheduling with risk, simplifies the steps of making the optimal strategiesof maintenance scheduling .
