Abstract:
A method and system are disclosed for optimizing load scheduling for a power plant having one or more power generator units. An exemplary method and corresponding system can involve detecting an event indicative of a need for adapting one or more constraints for an objective function used in load scheduling. On such detection, the objective function is analysed to determine adaptive constraint values for the one or more constraints for optimally solving the objective function. These adaptive constraint values can be used to solve the objective function and the solution of the objective function with the one or more adapted constraint values can be used to operate the one or more power generation units of the power plant.
