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

Abstract

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 real conditions of the self wind speed, the health condition and the output features, the wind farm active power reliability is ensured, the technical competition between the turbines is promoted, and the complexity of the wind farm active power control system is reduced.

Description

technical field [0001] The invention aims at the control and distribution mechanism of the active power of the wind farm, and in particular relates to a method for distributing the active power of the wind farm based on the second-price sealed auction. Background technique [0002] With the continuous maturity of my country's wind power technology and the intensification of competition in the wind power industry, wind power is gradually developing towards refinement, which has also continuously spawned new technologies. Unlike in the past, where there was only one or a few types of units in a wind farm, more and more wind farms customize the units according to the wind conditions of the installation locations of the units, so that the power generation performance, mechanical performance, safety performance, etc. Adapt to the wind conditions at the installation location, more effectively improve the return on wind farm investment, and optimize the reliability of the wind farm...

AI Technical Summary

Problems solved by technology

[0004] (1) The lack of necessary consideration of the characteristics of the unit makes it difficult to take advantage of the individual customization of the unit, and may even offset the advantages of the individual customization of the unit;

[0005] (2) Traditional wind farm active power controllers need to fully grasp the information of each unit to ensure the rationality of the active power allocated to the unit and comprehensively ensure the reliability of the active power of the wind farm. In the environment of unit customization, wind power equipment manufacturers will be very Pay attention to the protection of information related to technical privacy. It is difficult for the wind farm active power controller to grasp the complete information of each unit, which makes the traditional wind farm active power control mode face feasibility challenges;

[0006] (3) The power generation of each unit in the wind farm and the technical advantages of the unit are difficult to reflect in the power generation revenue, and objectively it is difficult to actively promote the development of new technologies by wind power equipment manufacturers
