Wind farm active power distribution method based on second-price sealed auction

The invention discloses a wind farm active power distribution method based on second-price sealed auction. The method is completed under cooperation between a wind farm active power controller and each wind turbine; the wind farm active power controller initiates power generation right auction to each wind turbine successively, and an auction end time is judged; according to the actual condition of the turbine, each wind turbine controller decides auction bid at each time; according to the bid of each turbine, the wind farm active power controller selects a turbine which wins the bid at each time according to a second-price sealed auction principle, and the corresponding power generation right is distributed to the turbine which wins the bid; and after the auction is ended, the power generation right acquired accumulatively by each turbine is the reference power for operation of the wind turbine. The method of the invention can promote the turbine to compete for the power generation right according to the rea
