Problems solved by technology

[0003] At present, the control of wind farms mainly includes output limit control, smoothing control, ramp rate control, and automatic power generation control. The control of wind farms in Jiuquan, Northwest my country mainly adopts the mode of output limitation, and the dispatch center issues the upper limit of output to the wind farms. , the wind farm only needs to control the output of the wind farm to operate in the area below the upper limit. This method allows wind power to participate in system scheduling to a certain extent, but fails to give full play to the control potential of the wind farm, making wind speed conditions and control performance relatively poor The output of good wind farms is limited, which is not conducive to improving the output characteristics of wind power

Abstract

The invention discloses a competition game-based cooperative wind power ramp control system and a competition game-based cooperative wind power ramp control method. By coordinatively controlling a wind farm cluster, wind farms and wind-driven generators, a central grid control station ensures that the output of the wind farms or the wind farm cluster can operate according to a given output curve or change rule, so that the ramp characteristic of wind power is improved and the connection of wind power with a grid is more friendly; according to the operating state of each wind farm, the central grid control station dynamically divides combined power generation unit substations, assigns subordinate wind farms, and issues a planned output curve to the combined power generation units; according to the actual output conditions of the wind farms and the planned output curve, the combined power generation units work out power adjustment magnitudes of the combined power generation units, and each wind farm controls the substations to compete for the power adjustment, so that respective benefits are maximized; and the wind farms control the substations to adopt different game strategies to compete to obtain total power adjustment magnitude of the combined power generation units, so that respective benefits are maximized.

Description

technical field [0001] The present invention relates to a limited control system and method for wind power generation ramping, in particular to a competitive game-based wind power ramping cooperative control system and method. Background technique [0002] Wind power ramp-up is an event in which wind power changes greatly in a short time scale. Wind power ramp-up will have a great impact on the safe and stable operation of the power system, resulting in an unbalanced power generation and consumption in the power system. The adjustment of conventional units alone will increase The operating cost of large conventional units reduces the economy of system operation. If the system backup is insufficient, it may even cause a large power outage. Through the coordinated control between wind farms, the output characteristics of wind power can be improved, the operating pressure of conventional units can be reduced, and the impact of ramping on the power system can be reduced. The g...
