Problems solved by technology
With the increase of the scale of the wind farm, the loss of power generation caused by the wake effect between the units increases. The traditional wind power control mainly considers the optimal power generation capacity of a single unit, and cannot achieve the maximum output of the entire wind farm.

Disclosed are a wind farm control parameter optimization method and system. The method comprises: establishing a wind farm simulation model, wherein the wind farm simulation model is established on the basis of the information of an actual wind farm; obtaining a wind farm simulation timing wind file, wherein a wind farm working condition table comprising all the working conditions happened to the actual wind farm is compiled according to the actual measured wind data of the wind farm, and a timing wind file used for simulation is generated; establishing an optimal control parameter, wherein an optimized target function capable of maximizing the benefit of the wind farm is established; and in the wind farm simulation model, simulating all the working conditions of the wind farm by using wind farm simulation timing wind file data, searching for the optimal control parameter of the target function under each working condition by using an optimization algorithm, and establishing an optimal control parameter database to store the obtained optimal control parameter. By obtaining an optimal parameter database, the present invention realizes the optimal control parameter of the target function under each working condition, and can optimize the control of the whole wind farm and achieve optimum benefit.
Description
Technical field [0001] The present disclosure relates to the field of wind power control, and in particular, to a wind farm control parameter optimization method and system. Background technique [0002] my country's wind energy resources are abundant and wind power is developing rapidly. As the scale increases by the wind farm, the loss of power generation caused by the latching influence between the units increases, and the traditional wind power control mainly considers the optimal power generation capacity of a single unit, and cannot achieve the overall wind farm. [0003] How to achieve optimal benefits through the control optimization of the entire wind farm is the main problem that is currently encountered. Inventive content [0004] In order to solve the deficiencies of the prior art, one of the purposes of this disclosure is to provide a wind farm control parameter optimization method, based on field test data optimization parameter table, and maximize wind farm earnin...
