The invention provides a method for making an annual dispatching operation plan for a power system. The method comprises the following steps: 1, dividing regions for grids; 2, determining the theoretical output time sequence of the annual wind power electric quantity and the annual load power electric quantity according to the historical output data, the predicted values of the annual wind power electric quantity and the predicted values of the load power electric quantity of various regions; 3, building a heating thermal power unit model, a non-heating thermal power unit model and a wind power electric quantity balance module inside the grids; 4, optimizing the annual wind power electric quantity and the thermal power electric quantity at each period by adopting an optimum start mode so as to determine the annual dispatching operation plan for a power system containing wind power. The method is used for making the annual plan which takes the operating characteristics of the wind power into account and provides important references for practical dispatching operation of the power system so as to increase the practical on-grid wind power electric quantity and farthest utilize the wind power.
