Description

technical field [0001] The invention relates to the technical field of wind farm control, in particular to a wind farm output power control system, which belongs to the technical field of wind power generation. Background technique [0002] Wind is a green and clean renewable energy that will be more widely used around the world. Wind farms are a tool invented by man. Wind farms use wind energy and combine it with a series of generators to generate electricity from wind. In large-scale wind power generation, the uncertainty of wind power and intermittent wind power fluctuations will increase the impact on the grid, and bring great challenges to power quality, stability and power generation control. The random fluctuation of wind speed makes it impossible to accurately predict the wind power. The wind power active power fluctuation is the error between the predicted value of the wind power output active power and the actual wind power value. Come challenge. In order to ob...
