Modeling method and application of power system dispatching model

The invention discloses a modeling method and application of an electric power system scheduling model, and belongs to the technical field of electric power system scheduling, the optimization target of the constructed electric power system scheduling model is to minimize the total cost of electric power system scheduling, and the optimization variables comprise the electric power output power and the thermal power output power of a cogeneration unit at each moment. The charging power and the discharging power of each electric vehicle at each moment are calculated; wherein the total dispatching cost of the power system is the sum of the total operation cost of the cogeneration unit and the total electricity purchasing cost of the electric vehicle in the whole time period T minus the total electricity selling income and the total standby income of the electric vehicle in the whole time period T and the total standby income of the cogeneration unit. According to the method, the standby power capable of being pr
