Method and control system for scheduling load of a power plant

摘要

The present invention relates to a method for optimizing load scheduling for a power plant having one or more generation units. The method comprises the steps of analyzing the operating state of one or more components of generation units in terms of one or more risk indices associated with one or more components of generation units; updating the objective function that reflects the state of one or more components of generation units; solving the objective function to optimize schedule of the one or more generation units and operating state of one or more components of generation units; and operating the one or more generation units at optimized schedule and operating state. The invention also relate to a control system for scheduling load of a power plant having one or more generation units. The control system comprises an optimizer having a single objective function for optimizing load scheduling which includes maintenance scheduling and for optimally controlling processes of the one or more generation units. The optimizer utilizes a plant model component and a failure model component for load scheduling optimization.
