Problems solved by technology

If the power system cannot be effectively controlled and there is an imbalance between supply and demand, it will affect the reliable power consumption of the load and may even cause a large-scale accident in the system
[0003] Due to the limited peak-shaving capacity of the system in the "Three Norths" region and the influence of grid transmission capacity constraints, wind power "abandoned wind" phenomenon is serious, and the actual grid power of wind power and the predicted wind power may have a large deviation

Abstract

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.

Description

technical field [0001] The invention relates to a method for generating electricity with new energy, in particular to a method for formulating an annual plan for dispatching and operating an electric power system. Background technique [0002] The power system is a complex dynamic system, and its safe and stable operation essentially requires a balance between power generation and load demand at all times. If the power system cannot be effectively controlled and there is an imbalance between supply and demand, it will affect the reliable power consumption of the load and may even cause a large-scale accident in the system. [0003] Due to the limited peak-shaving capacity of the system in the "Three Norths" region and the influence of grid transmission capacity constraints, the phenomenon of "abandoned wind" in wind power is serious, and there may be a large deviation between the actual grid power of wind power and the predicted wind power. In order to maximize the wind pow...
