The invention provides a user-oriented generation schedule modeling method. The method comprises the steps of through creating an optimization object of a generation schedule, confirming and setting constraints of a generation schedule model and setting an optimization target of the generation schedule model; and creating a user-oriented generation schedule model on the basis of the constraints and the optimization target. The method provided by the invention is simple, flexible and effective and has the advantages that the model of a real scheduling object can be built and a linear combined entity formed by single objects can also be built; and the flexibility and the extendibility of the generation schedule model are greatly increased, the extension is realized with no need for any programming capability and once a model is built by a programmer according to descriptions, a user can modify the model according to the needs, so that the energy-saving economic scheduling efficiency in electric power industries is increased.
